If you receive a call from an unknown number, don't answer it.
Or else it will be your last call.
Who is this calling early in the morning?
A WHILE AGO
Mom… Wake up, mom.
Why do you wait for me every day?
What is the time?
The food must have become cold.
There's no need for that.
Tell me this, how many times have I told you,
that this is my work and I'll be late every day.
Is it necessary for you to wait for me? Am I a kid?
No matter how big you grow
you'll always be my little Ayu.
The one who would get scared at night and come and sleep in my bed.
Yes, I know.
But listen… If something happens to you
or if your health goes bad?
Are you laughing?
It's the truth. If something happens to you, who will take care of me?
Nothing will happen to me.
I've made your favourite rajma' and rice.
It must have become cold. I'll come.
No, no… There's no need for that.
You go to your room. I'll manage myself.
I'll freshen up and have my food. Okay?
You spent the whole night waiting for me. Come on.
I'll continue waiting for you
until my last day.
I'm your mother, right?
- Yes, go on. - Got it?
Go and sleep.
Make sure to eat.
Yes, I'll eat, mom. Go and sleep. Good night.
Mom!
Mom…
Mom… What happened to you?
Mom! Mom… What happened?
Mom, open your eyes. Mom… Mom…
Nothing will happen to you. Open your eyes.
Open your eyes. What happened?
Mom… Nothing will happen to you.
I'm here. Just a minute.
Mom, mom…
Brother, open the door. Please.
Please.
Nothing will happen to you, mom. Hold on.
- What happened to her? - I don't know.
Thank you so much.
What's happening? Why is everyone's phone blasting?
Mom, nothing will happen to you.
We're almost there.
News is just coming in that mobile phones are suddenly blasting
at different locations in the city.
There is chaos in the city.
Yes, mom… We're almost there.
Please check my husband. His leg is hurt.
- I'll come. - Listen to me.
Sister… That…
Hurry up.
There's not a single doctor here. What kind of a hospital is this?
Anyone, help. Help! Anyone!
Is there anyone? Sister. Sister…
Please see, she's bleeding a lot. It's an emergency.
Please do something.
Sir, there are a lot of casualties. It's a police case. It'll take time.
I'm from CID. ACP Ayushman.
- Sorry, sir. - Please.
Who is she? Is she your mother?
More than a mother. Please.
- I'll do something. - Yes, please.
Bring the stretcher.
- Stretcher. - Bring the stretcher.
Stretcher. Come on! Please bring it faster.
Hurry up.
Carefully.
- Take it easy. - Please take her.
Please open your eyes, mom. Nothing will happen to you.
I'm here with you. Everything will be fine.
Doctor, please check.
Please check with my mother. She's bleeding a lot from here.
Yes, the bleeding is severe.
- Pulse is unstable. - Unstable?
Take her to the ICU quickly. Please wait outside.
Pulse… Pulse, unstable? Doc…
- Hey… - No, don't answer your phone.
No one will answer their phones.
Put your phones in aeroplane mode.
Don't answer your phone.
All the phones are blasting. You will lose your life.
Is your mother okay now?
We heard that she was also a victim of the mobile phone blast.
Sir.
Sir. Please get a hold of yourself.
There were only two people in my life, who were my own.
First, ACP Pradyuman sir
and the second one, my mother.
She was the one who brought me up.
I've already lost ACP, sir.
And my mom is fighting between life and death…
You… Please don't lose hope.
Nothing will happen to your mother.
Whoever has tried to turn this city into a pile of explosives
will not be on the run for long.
Did you find out anything about how these cell phones, mobile phones
are turning into bombs?
The call comes from an unknown number.
If anyone answers the call, the phone blasts.
We are finding out who has done this and how.
Make announcements on TV, radio and all other media
that no one should answer any calls coming from unknown numbers.
We've already spread the news, sir. Please take care.
We will manage everything.
We've handed over some of the phones that blasted.
I don't think he has also seen anything like this before.
- Is the van ready? - Yes, sir.
We've alerted all the news channels via satellite.
Messages have been sent on the radio and social media.
There might be panic.
- But we've spread the awareness. - Good.
Sir, is Ayushman sir's mother okay?
She's in the ICU. She's stable as of now.
We have to go to the forensic department quickly.
Why are the phones blasting?
Is there a defect in the phone? Or is it some other reason?
- Sir, this cannot be a defect? - Why?
All the phones are from different companies and different locations.
You're right.
If there was a defect,
all the phones would be from the same company.
The phones here are from different companies.
All the batteries have exploded.
Sir, the batteries used to blast earlier, too.
But how can there be blasts
in the same city, all in one day?
Sir, that's what we don't understand.
It feels like someone has intentionally
made all the phones alike.
You're right.
He's answering the phone.
Do not answer calls from unknown numbers. The phones are blasting.
You could lose your life.
Do not answer calls from unknown numbers.
Take care of yourselves and inform others, too.
The phones may be from different companies
but they have one common factor, and that's the network.
Sir, this does not look like a normal terrorist attack.
Someone has done this remotely.
Someone knowledgeable.
And see the weapon they've chosen, it's a mobile phone.
It's become everyone's life, and now it'll be the reason for their death.
And sir, look at the timings.
All the blasts have a similar pattern.
A new blast has happened every two to three minutes.
Sir, there have been 200 blasts so far.
God knows how many more there will be.
We have to stop this as soon as possible.
Bhoomi, do one thing.
Find out if there is a common connection among all these phones.
Maybe an app which was installed on all these phones.
Maybe that's the app that's becoming a trigger for the blast.
- Check, Bhoomi. Check. - Yes, sir.
There's a chip inside this one, too.
It's the same chip.
Another phone, another chip.
How is this possible?
Sir.
Look at this. There is a chip in this battery, too.
Oh, yes.
That means this chip is in all the phones that blasted.
But how?
Dr Salunkhe, any info on these phones that blasted?
Anything that comes to our lab speaks
be it a dead body or anything else.
What did these phones say?
They did not just speak, they showed, too.
Look at this.
Do you see this chip?
Every burnt phone that we got from different locations
have this extra chip with the battery.
- Extra chip? - Yes.
And it's not factory-made.
I think through this chip
they have made a remote trigger.
The planning seems to be very good.
They first made a programme
and then fit these chips inside the mobile phone
and then sent a signal from the tower to the phone with the chip.
Then, an unknown call is received.
As soon as the call is answered
the chip is activated
and the mobile phone overheats and explodes.
Wow, Abhijeet.
You made the right analysis.
I'm just learning, sir.
You've already learnt.
The one who is doing all this
is hiding in some corner of Mumbai.
The one who has done this is very clever.
No matter how vicious he may be
the signal has reached the CID. He cannot escape now.
Sir, I checked the data on all the phones.
There is something common.
Everyone had installed an app from an unknown link.
Abhijeet, that app is the programme.
Sir, I wonder how many people might have installed the app in the city.
Sir.
This means no one is safe in any corner of the city.
Sir, you said that this chip
reacts at a special frequency.
We have to find out the source of this signal.
Wherever the signal is originating from,
that's the source of all this commotion.
Until we find the source
the entire city is sitting on a mountain of explosives.
Sir, this chip does not belong to any registered company.
The serial number is also very old.
But I've found a match in the database.
This chip was registered for the first time
during the time of the Ecomaze Project.
The name of the project lead is Dr Advaith.
Ecomaze… Sounds familiar.
This is used to control signal overload, right?
Yes, sir. It managed the signal traffic between the tower systems.
Sir, this means this technology was made to help people.
And now it's being used to blast phones.
- How? - Sir, look at this.
The chip design has recently been duplicated.
Huh?
Two months ago, it was re-activated by GRN Devices Lab.
The name of the technician is Karan.
GRN Lab. Karan?
The most interesting thing is
the name of the software code written for this chip
is TitliOverwrite Protocol.
I'm sure this is the code name.
Sir, maybe the one who created this programme
used the name 'Titli to hide their real name.
Correct. We need to map the signals
from where this signal is originating.
Once we find out where it's coming from, we can get the criminal.
Sir, I know a person
who is an expert in signal mapping.
The one who has made this duplicate chip, Karan
we have to find him first.
Find out where Karan is hiding.
No!
You're courageous, ACP.
Now you are part of my network.
You answered.
Now the city will listen.
Goodbye, ACP.
The voice sounds very familiar.
Who could it be?
Whoever he is, wherever he is,
he cannot escape from my hands.
- Sir… - Hmm.
Karan's location is somewhere nearby.
Is it?
Stop the van.
Sir, she is Yasha. Telecom software expert.
As you said, we need a person
who understands signal mapping and tower relay.
- There can be no one better than her. - Hello, sir.
Sir, I have taken training in Bhoomi ma'am's AI workshop.
I've also learnt how to do tower modulation.
I noticed the irregular signal bounce from some old towers.
When I heard this news, I felt I must show you this data.
Okay, then.
Remember, whatever analysis you do,
you will do it through the CID systems.
You will not use the network through your personal phone.
All right, sir.
Sir, you're here? You should be with your mom, right?
I know, Pankaj… I tried.
But…
A CID officer cannot stay away from his duty for long.
So, come on.
Let's end this game together.
Sir!
Yes, Kritika.
Look at this, sir.
This is the last location.
This is Karan's location.
JD Nagar, Sector 5.
This is just five minutes away from here.
Sir, I saw a few different signals in this place. This may be the one.
Okay, there's no point wasting time here. Let's go there.
Okay, Yasha. You'll be connected with us through the CID systems.
We want every small detail. Okay?
Sure, sir.
Karan!
Don't run, you'll get shot.
Stop!
Hey!
- Sir… sir… - That's enough, son.
Your server is down.
Sir, I didn't do a thing. I'm just a technician.
You made a chip that is seen within the exploding phones.
Your chip is killing people, do you know that?
I was given the designs, sir.
I was told to use the old designs to make new chips.
I was told I would be paid for it.
Who gave you the designs?
Sir, it was just a voice.
I could only hear it, never see it.
Whose voice? Your client?
Sir, they've been missing.
Missing or hidden? We will find him.
This chip, how did you get them in these phones?
Through a free phone repair campaign.
I would go to people's homes and take their phones, citing service.
I would add the new chip to it.
You did this, or did you get someone else to do it?
I just hired the technicians.
I thought it was testing.
Arrest him. Seize all the hard drives and chips in here.
He is just a pawn.
The true mastermind is out there.
We need to go to the Ecomaze research lab
that's been closed for three years.
We'll find some answers there.
Hey!
We've found something here.
What?
- What is it? - We can hear voices.
Dr. Advaith! Dr. Advaith, are you alright?
Dr. Advaith!
Don't be afraid. We are from the CID.
Are you alright?
I…
I was locked in here on somebody's instructions.
Who did this? Who was it?
He stole my system.
I… made it…
for the city's towers and roads.
He made it a bomb.
Who did it?
I got a message on my computer from them.
Here, take this pen drive.
There's audio…
Audio?
You may be wondering how the CID has come so far.
This is no small team.
The whole world knows your name.
That is why I wanted the CID to be part of my game.
The fun of playing chess with an expert
is unlike any other.
Sir, this is an open challenge.
Dr. Advaith,
he was a means to an end.
You may have thought that you caught me.
That is my victory.
This video was made for us.
I'm not afraid of you, CID lot.
I just need a while longer.
The tower is ready. So is the audio.
The next signal will rock the city.
It looks like he had all of this planned.
Getting CID to Dr. Advaith.
Perhaps he is trying to send us on a diversion.
Either Dr. Advaith is lying,
or he is already part of someone else's game.
He has already planned something big.
Could you trace the location?
- Sir! - Yes?
We've traced an unusual tower signal.
It changes every ten seconds.
It means that the source is moving.
- So it's not a fixed tower. - No, sir.
This is from a moving van.
I've got the location down to one square kilometre.
Industrial zone, Sector 9.
Hold on.
Look here. This is the current hotspot of the signal.
The signal is active, the blast is on its way.
Ready the team.
Inform the backup unit, we are leaving.
Sir, the signal is being traced to this van.
Same frequency.
The one detected during the mobile blast.
Nobody knows
that this van is a ticking bomb.
The whole system is in place.
The blast is ready.
We have very little time.
Cut all the connections.
No, sir, if we cut something wrong,
it will instantly trigger the signal.
Remote deactivation is not safe.
We are trapped.
He knew we'd find this van.
If someone picks up that call, then everything will go black.
Everybody out!
This van is to destroy us.
Come on, fast!
That was a close shave.
But we know
that this man threatens and isn't scared to execute.
Sir! The bureau's security has been breached.
Someone is stealing our data.
Come on, let's go.
Sir, the system is being breached.
Someone is trying to hack our internal server.
How much data have we lost?
Sir, 75 per cent.
It is being transferred very quickly.
CID is on my web now.
Shut it down, quick!
- Sir! - Yes?
The locker is safe.
Hey!
Where is Yasha?
Where is she?
CCTV! Check the CCTV footage.
Sir!
Yasha left three minutes before the breach.
This was planned.
This man is more than a voice.
He was listening in on every move of the CID.
CID was in his control.
She betrayed all of us.
We couldn't see through her.
Bhoomi, you are part of the CID.
You recommended Yasha.
She hacked the whole system. You didn't realise that?
Sir, I didn't know about her intentions.
Sir, I thought she was an expert and she'd help us.
They had transferred 99 per cent of the data.
If we didn't shut it down in time, we'd lose everything.
Do you have any idea what would happen?
You gave her access.
Yes, sir, I gave her approval. She was working in the control room.
She was in front of everyone. I assumed it would be safe.
Bhoomi, you can't trust anyone in our profession.
Did you check her background?
Sir, she gave me the documents.
I didn't think they would be fake.
Bhoomi, either you made a mistake or
you are involved in this.
You are dangerous to the CID.
Sir, I would never work against the CID.
Only time will tell.
Now, you are part of the investigation.
Sir!
What?
Sir, the first van blast had a file in it.
The old file mentioned Bandra Industrial Zone several times.
Sir, I know this place well.
A trial van belonging to a telecom company
would always be parked there.
Yasha didn't just make one van.
There was a backup ready as well.
One for us and one for the city.
Sir! We received a signal trace.
Sir, I think there will be a blast there.
Let's go.
This game ends tonight
or this city goes up in smoke.
Sir?
Sir, the signal is confirmed. This van is the final source.
That tower is the source.
I'll go in the van.
Alright. I'll check the tower.
There are so many wires here.
Where is the control panel?
Sir! There it is.
Shoot!
We don't have long.
Sir! Are you sure which wire triggers it?
If you cut the wrong wire the whole block will go up in smoke.
Yasha!
We'll see.
That was your last step.
This is what brought you to me.
I have been suspicious ever since you got that van so quickly.
Are you here alone?
Should I call this bravery or stupidity?
I'm from the CID. I believe in my choices.
I trust the system.
Impressive.
You are smarter than I gave you credit.
But not anymore.
You broke into our systems.
And my trust.
It's done.
We're safe.
Come on. Come on!
It's done.
He was talking about blowing up the city.
He's gone quiet now.
Game over.
Sir!
Bhoomi?
Oh!
You have brought your claim to innocence.
Need to make tough decisions for the CID.
- Sometimes, for myself, as well. - Good job, Bhoomi.
I'm a part of the CID, sir.
I will always be a part of it.
Your game is over, Yasha.
Only the truth now.
Who do you work for?
I didn't work for one individual.
I just worked.
I would get paid.
I didn't care about who paid me.
What was the work you were given?
To enter the CID systems and hack it from the inside.
To activate the voice protocol.
Voice protocol?
Yes, I would be given a single instruction.
To look into their eyes
win their trust and steal everything.
I would get payment in a new account after every task.
My work was quite simple.
To sit under your nose
and steal your systems.
Who was the mastermind?
I was just a pawn.
The game was being played by someone else.
The audio is still on the network.
The voice?
The voice is the mastermind.
Till you think everything is over,
he will press the next button.
This voice,
is it Barbosa?
Ayu,
son, you didn't pick up my calls.
I will pick up your calls, all the time.
You haven't slept.
I was scared.
I was waiting for you to wake up.
So I could sleep on your lap.
Come, dear.
You can sleep on my lap.
Hold on.
