A man is murdered and we are shown clips of it.
PUNE: Police officers Ajay and another one (who we don't know the name of - He is ACP's real son) receive a call. They immediately reach a hotel and go to Room 406. There, they find an old man and they demand him to put his hands up in the air. The old man turns around and we see that it is ACP Pradyuman. The police officers ask him what he is doing here. ACP Prad says that his name is Sagar and that his friend Karan lives here. He saw that the door was opened and wanted to see his friend. But still, Ajay and the other officer arrest him and take him to the police station.
They interrogate ACP Pradyuman, but Prad tells them that they should interrogate the killer and not him. Prad further says that his lawyer will soon be coming here to bail him out. Just then, Sagar's a.k.a Prad's lawyer comes in. The lawyer (Abhijeet in disguise) asks the police officers if he could have 5 mins alone with Sagar. Officers leave.
Abhijeet asks Prad what happened. Prad says that Karan was his friend's son. Karan was a detective and he had called him to Pune for a case, which he couldn't reveal over the phone. Karan had even told Prad that he must come to Pune in disguise and not tell anyone that he is ACP Pradyuman from CID Mumbai. So, Prad caught a plane from Mumbai and reached Pune. He went to the hotel where Karan had been staying, since Karan booked a room close to his, ROOM 405. Prad had asked the receptionist if Karan was still in his room. The receptionist said that Karan had left with a lady, who looked like a model 2 hours ago. ACP Pradyuman went to the 4th floor and when he was going to open his room door, he saw that Karan's room door was opened. So, he went inside to check what happened. He saw that many things were lying around. Then, he came upon a carpet, which was cut in half and found something inside it. Then, after that, the officers had caught him then.
Sagar a.k.a Prad shows his lawyer, Abhijeet what he found - it was a matchbox and it said SAM-X. Prad says that perhaps Karan wanted to give him a clue and this might be it.
Mumbai - In Karan's Office: Daya and the lady inspector are there (sorry! still don't know her name). They are searching thru his office. Prad calls Daya and tells him that Karan always had a habit of taking down notes on a note pad, while he was on the telephone. Daya checks the desk and finds a note pad. He finds that it says SAM-X.
Lone house: Prad investigates and goes inside the house where Karan was murdered. Prad hears a noise and goes inside to find a dead girl. At the same time, the inspector comes in and arrests him. Abhijeet and Daya come in and tell him that they are Inspectors in the CID Bureau from Mumbai. Prad then takes out his wig and tells him that he is ACP Pradyuman, CID, from Mumbai.
Pune: The two inspectors come back and tells Sagar and the lawyer that they are free to go now. Prad says that he didn't do anything! Prad then asks the inspectors if they know who SAM-X is. The inspectors laugh and tell him that SAM-X is a very rich guy who owns chain of hotels here in Pune.
Prad calls Daya and the lady to come to Pune to join them.
After a series of events, they find out that SAM-X's' wife is Lavanya and he also has a niece named Ria.
Prad tells the officers to disguise and go into SAM-X's hotel and find out about the MATCHBOX incident.
The lady inspector goes in and tries to flirt, but doesn't get a membership b/c she didn't have any connections. Next Daya enters and purposely bumps into Ria. Ria is immediately smitten by him. They talk and Ria flirts with him.
Meanwhile, in the same hotel, Abhijeet disguises as a waiter and enters into a manager's room. He hears the manager come in and immediately goes outside the window and holds on to it. He notices that many people come in there and give huge sums of money to the manager and in return, they get a matchbox. He also observes a fat female doing the same thing. Abhijeet reports this to Prad.
Meanwhile, Prad (in a disguise) is outside observing SAM-X's wife Lavanya. He sees that she is in the car and the inspector Ajay is with her too. Ajay comes out of the car with a package. Immediately, Prad goes towards Lavanya's car and sits inside. Lavanya revolts, but Prad asks her if she knows a guy named Karan. She says no and is scared. Prad tells her that Karan has been murdered. She is shocked and screams Prad to leave her.
Bureau: Abhijeet reports his findings to everyone, and so does Prad about Lavanya. Prad orders Abhijeet and the new lady officer to go into the murdered girl's workplace (a flower shop).
Abhijeet and the new lady inspector dress up and act as husband and wife and go inside. Just then, Abhijeet sees the fat lady that he saw in the manager's room. He follows her and finds that she lights the matches, puts it in the can, and in return she gets a drug cocaine. Abhijeet is surprised and reports this to Pradyuman.
Prad goes to Ajay's house to find out why he is tied in this case. They find out that Ajay is murdered. Prad speculates that he too must have been part of the Drugs business.
Meanwhile, Prad asks Daya when he will be meeting Ria. Daya says tomorrow. Prad tells Daya to show the matchbox to Ria and find out her expression.
Tomorrow in the club: Daya loudly speaks on his phone that the lunch is cancelled because his friend is late. He sees Ria talking to a man. He purposely does this so that Ria can hear him. Ria immediately comes towards him and asks him if they can have lunch together. Daya says OK.
Bureau: Lavanya is there and confesses that she had hired Karan because she sensed that her husband was having an affair. She says that she didn't kill anyone.
Restaurant (all alone outside): Ria wants to light the candle, but can't since she doesn't have a matchbox. Daya immediately takes out SAM-X matchbox and tries to light it. Ria is scared and her eyes widen out (she is panicking). She tells Daya not to light with them and asks him to change the music. Daya goes over to change it.
Ria immediately takes out a knife and goes towards Daya. Before she could stab him, Abhijeet, Prad, new lady inspector and Fredricks stop her.
Prad asks Ria why she killed three people. Ria says that she killed Karan because he found out that she was taking drugs. Her life was in danger because uncle found out that she was showing the world that she was taking drugs and that his business would have been exposed. Ria killed the girl to divert the officers' attention. She also killed Ajay because Lavanya had an affair with him, but Ajay loved her, but he found out about her business with drugs and so killed him. She says that she killed all of them because her life was in danger.
