-Vicky... -Tanya, where were you?
-This is too much! -You should've at least told me.
I think there's something in that footage the killer wants.
But first, we need to talk to Mehek.
Which means we'll have to go to the hospital.
Are you crazy? It's not safe at all.
But...
-Mehek? -Guys, until this matter is resolved,
both of them will stay here with you. Okay?
Mom, Mehek can't stay here.
Come on, Tanya. This isn't the time for this, okay?
Besides, your friend wants to talk to you.
Good. I want to talk to her too.
Go on, say what you have to.
Richa, are you going to say something?
Promise you won't get mad.
-Please. -You're scaring me now, just tell me.
Those hard drives Knock Knock wanted...
-I stole them. -What?
Are you out of your mind?
Richa, how could you just...
I didn't know things would get this bad, otherwise I would've...
But why did you need them?
I just
needed the money.
If you needed money that badly, you could've just asked me.
How can you be so stupid?
It's not a one-time thing, Tanya.
I need money every two weeks.
Why?
Are you doing drugs?
No.
I take pills.
Weight loss pills.
Maybe you never noticed, but...
I'm not size zero like Simmi.
Or fit and gorgeous like you.
You're normal, Richa. You're fine.
You're completely fine.
What if I don't want to look normal?
I want to look hot and sexy too.
But you are hot and sexy.
But I'm not slim.
And in our society, slim means sexy.
That's why I had to get those pills from Joshua every two weeks.
I don't know. There's...
There's this pressure to look a certain way.
Of course, I understand, okay?
I understand! I'm a girl too, I live in this same world.
I didn't know you were so troubled about your weight.
You're my friend.
You should've just talked to me.
Sorry.
What's done is done. Let it go now.
Stop crying, okay?
You're sure you're not mad at me?
I am mad.
But I'm more pissed off at Knock Knock.
Richa, promise me, no more secrets.
I promise.
And listen...
Confident girls are the hottest, okay?
And you're more confident than me.
Who said you're not hot and sexy?
After Knock Knock, we'll beat him up.
Let's go.
Thank you, Tanya. I'm sorry.
Guys, where's Mom?
No idea.
Listen, Tanya...
I know you like Rohan.
But I still think he's dangerous.
No.
Not Rohan.
Mehek is the real danger.
What's all this whispering about?
Tell me too.
After the attack on Simmi,
when I went to meet Mehek for the first time,
she said something very strange.
How could you do this? I've never seen a bigger lowlife than you.
I am so sorry, Tanya.
I didn't know things would go this far.
It just went too far, I'm so sorry, I didn't mean it.
I told Rohan to talk to her
and get some information.
And how can you say
that those two aren't involved?
Mehek...
At the hospital you said something very strange to me.
What did you mean by "it went too far"?
"I didn't mean it."
Tanya, what are you saying?
I have no idea.
That day I was so medicated, I must've said something random.
Just forget it.
Tripathi sir has been murdered.
Ammonia is missing, you and Simmi were attacked.
What else needs to happen for you to finally tell me the truth?
Stop it, Tanya!
Whatever's happening here has nothing to do with me.
I'm not responsible for that, so just back off okay!
No fricking way!
Oh, my baby, how are you?
Look at you.
Where's the colour on your face?
-I'm good now. -I knew it.
Hospital clothes?
That's why I brought a change of clothes for you.
See. Just like mine.
You didn't have to, babe, but thank you.
But I wanted to.
Believe it or not, I really care about you.
By the way, what's the commotion going on in this city?
Any idea?
Some dead body or something.
Oh my God! Ro-Ro darling is here too.
Is this like a party or something?
But please remember, the real party is tomorrow
at my farmhouse.
Hey! This year's Halloween Party.
-You remember, right Mehek? -Of course.
My mom is out looking for the killer, and you want to party.
The party will also be killer.
Who knows, thanks to Foomer...
Knock Knock might show up too.
Are you crazy?
Anyway, Mehek, please put on these clothes.
What just happened!
What happened?
Guys, look at this.
Ammonia.
Oh my god! Her body is in the lake.
And do you remember who we saw near the lake earlier?
Adheer.
What's going on?
Ma'am.
Ma'am...
Ma'am, please, one question.
First a girl is attacked.
Then a police officer is murdered.
And now another girl has been brutally killed,
what is the police even doing?
When will you catch that killer?
You'll get answers to all your questions.
The police will soon catch the killer.
No more questions please.
Ma'am, that's not even an answer.
Ma'am, please, tell us something.
Yes, sir.
Yes, sir. I'm handling everything.
We're going to nab him soon, sir.
Yes.
Take some water.
I'm really scared.
Don't worry, Simmi.
All of us friends are together.
Don't be scared.
We're with you.
We'll beat that jerk up right now.
Like Kavita ma'am said,
if we all stay together, we'll be safe.
By the way, Random, even you got dragged into this Knock Knock mess.
You must be wondering why you even became friends with us.
You all are my friends?
Of course.
Otherwise why would we always hang out together?
Really, Tanya? You mean it?
I mean, all these years in college,
we never really became friends.
That's because more than talking to us in college,
you were busy staring or stalking us.
To become friends, we have to know each other.
And now we know you're a solid 10 guy.
You located Mehek's phone at Simmi's,
helped out her aunt, and...
even ran after Knock Knock to catch him.
Richa is right.
I can't believe that you guys,
the coolest and most happening people in college,
are my friends.
Did you just say we're the most happening people in college?
Yes.
Richa, I'm not stuck.
I'm really lucky.
Come on.
Guys, Kavita ma'am just messaged.
She's called me to the station.
Okay. Do you need any help?
Phone... Random.
Please, if possible, check Mehek's phone.
I think she's hiding something from us.
Yeah.
Richa, Simmi, Tanya...
promise me one thing,
that after all this is over,
we'll still be friends.
Don't get so emotional.
We're lifelong friends now.
Hello, ma'am. You called me?
Hi, Randeep. Meet him...
Siddharth Menon, our new IT expert.
Hi.
Sid.
Hello.
Ma'am, why a new IT expert?
I was helping you, right?
Yes, son. You've helped us a lot.
But this matter has gotten very serious now.
We're under a lot of pressure.
So, we needed a professional.
Exactly.
This isn't just a case anymore, it's become news.
So whatever you've done so far, hand it over to me.
Give me all the information, all the data, whatever you have.
Ma'am, I've been on this case from the start.
So, I can still assist him, right?
I'm really sorry, but I prefer to work alone.
Randeep...
You said you couldn't find any social media presence for Adheer.
No Facebook, nothing, you couldn't trace any history.
-No, ma'am. -Ma'am, let me give it a try once.
Yes, please do. Please do.
One minute.
Hello. Inspector Tambe?
It's going on.
Can you do me a favour?
The files from my Ratnagiri posting in 2014 to 2016,
can you please send me a copy of those?
It's a bit urgent.
Thank you so much.
-Siddharth... -Yes, ma'am?
This boy Adheer is definitely hiding something.
Please find out who he is,
where he came from. Just do a complete background check on him
and get back to me as soon as possible.
I'll do it right now, ma'am.
-Thank you, ma'am. -Thank you, son.
Richa...
Simmi.
Thank you.
Sonia.
Mehek.
What happened? Why do you look so upset?
So many years of friendship and
I can't trust anyone.
Simmi lied to all of us
about her job, her life.
Richa used to buy pills from Joshua.
I stopped trusting Rohan a long time ago.
And Mehek too.
All my friends are like this.
How can I trust anyone?
So, that means, Vicky is off the friend list now.
Very good.
Because you're my bro.
And you're the one I trust the most.
That's why I'm telling all this only to you.
Knock Knock is right here.
Among us.
It's someone from this group.
So what do we do?
Should we call Aunt?
No, she's already very stressed.
I have to figure this out on my own.
You just said "stressed" and dad called.
Two minutes.
Yes, dad.
Dad, everything is fine.
I'm at Kavita aunt's house.
These news channels really exaggerate things.
There's no such criminal roaming in the city.
Tanny!
I tried talking to Mehek.
She didn't say anything but
I don't think she's involved in all this.
And yeah, about the app...
What? What happened?
What happened?
-Actually... -Rohan, you'll never change.
Any girl who comes and talks to you nicely,
you skip the hello and go straight to making out!
First Mehek, now Ammonia.
Tanya, it's nothing like that.
Just hear me out once.
You know Mehek and I had a very toxic relationship.
Even Ammonia saw all that, and she just came to talk to me.
-She just wanted to talk to me... -I'm not an idiot, Rohan!
Just stay away from me.
What if you're Knock Knock?
-You might be enjoying these games. -Bullshit, Tanya! Come on.
You were the one who set up UPI on my phone.
And you know all my passwords.
So? That doesn't mean I did anything, okay.
You're doubting me because of a silly app.
I came to tell you that I also downloaded the app.
I thought I'd try to figure out...
One minute.
What happened?
Shit!
What?
Your app...
It's fake.
Look, there's a blue border on my app, yours doesn't have it.
See.
I messaged the app developers.
Their app is being used in serious crime, they should know what's going on.
-So what did they say? -They replied, one minute.
Thank you for your query.
In our database, from this email ID,
Tanya Arora has not downloaded the app.
What?
Hello?
Random, the app on my phone is fake.
Oh, shit!
I missed such a big thing.
Tanya, listen to me. That psycho sent you a malware app.
He has hacked your phone. This is not good.
Random, you were the one who sent me the app link, right?
Me?
Tanya, when did I send a link?
Do you remember the "Night of Fear" party?
No, Tanya, I never sent any link. I swear.
Do one thing, check that link in the message again.
-What? -Just check it.
-Invalid. -Invalid.
Shit.
Okay, I'll talk to my cousin.
He's a genius at this stuff. He'll figure something out.
Okay. And Tanya,
Knock Knock being your friend
is not necessary.
He's getting all your info by hacking your phone.
Tanya, switch off your phone.
Throw it away, burn it!
Whoever he is...
He's listening to everything you say.
He can see us.
Shit.
Pick it up.
Hello, Tanya.
You trust your friends a lot, don't you?
So tell me, who's next?
Stop all this.
This is Mehek's plan, right? What do you want?
Mehek.
Okay. As you wish, Tanya.
-No... -Mehek it is.
No! No!
Let's go!
Where is Mehek?
-I don't know. -What happened?
Sonia!
-Stop! -Oh God!
Sonia? Sonia?
She'll be fine.
Sonia?
Vicky!
Vicky?
-Vicky, are you okay? -Over there...
Random?
Just because people look a certain way,
doesn't mean they really are like that.
While staying with all of you,
his eyes were on all of you.
In fact, he almost convinced all of you
that I was Knock Knock.
Just because Random is Knock Knock
doesn't mean you're a trustworthy person, Adheer.
If Sonia had died, would you have taken responsibility?
Stop fighting!
Random was Knock Knock and he's dead.
That's all that matters.
And he did so many shady things that it proves he was Knock Knock.
He was the attacker.
He was the one who sent the Knock Knock app link to Tanya.
He had even said...
"Random, you were the one who sent me the app link, right?"
"No, Tanya, I didn't send any link. I swear."
He was lying.
First he attacked Mehek,
then Ammonia, and he even tried to kill me.
I get all that, but
how could Random be Knock Knock?
And how did he manage to catch Rohan so easily?
What's the big deal?
Simmi can beat up this bag of bones.
When Simmi was attacked,
he was with mom, right?
No.
I had called Randeep after Mehek's phone pinged.
Guys, I have something to tell you about Randeep's death.
He slit his own throat?
The knife was still in his hand.
I think he wasn't mentally stable.
I need a proper and detailed report.
Yes.
Ma'am...
I traced his cell phone location over the last two days.
He had told us that when the hospital attack happened
he went to the lakeside after Knock Knock,
but GPS clearly shows
that he was at the hospital at that time.
Which means he killed Tripathi?
And ma'am, you asked me to check Tanya's bank details.
-Yes. -No debit records.
So the UPI transfer Joshua received...
The money that Joshua got,
it was transferred by Randeep from a different ID.
The bank just confirmed it.
He totally played us.
A young boy fooled the entire police department.
Textbook psychopathic criminal behaviour.
-Explain in Hindi! -In simple words,
criminals like this look normal,
but they can manipulate.
Random also won over Kavita ma'am's trust
and became part of the case.
So that when an investigation happens, he could mislead it
and none of us would suspect
that he was Knock Knock.
Guys, one more thing.
Randeep left a message before committing suicide.
For you, Tanya.
This is all we could recover from his phone.
'This shouldn't have happened.'
I swear, I thought it would just be a silly prank.
Nothing beyond that. I'm so sorry, Tanya.
I'm so sorry!
I know you'll find out
that I was involved in all this
and you've already found out about the app.
Mehek, I did all this only and only for you.
I love you, Mehek.
I've loved you since day one.
Mehek, please tell the truth now.
Tell them this was all just a joke.
We've made a huge mistake.
If possible, please forgive me.
And don't forget me.
