Professional hitman Mangal Singh takes a contract to kill stock market scamster Manu Gupta in front of the Goa High Court where he is to undergo a trial. Mangal Singh plans to do the job from a hotel room which is opposite to the court.
Suresh Sudhakar, a press photographer is sent to Goa to cover Manu Gupta's trial and checks-in the same hotel next to Mangal Singhs room. Sudhakar tries to meet his ex-wife Pinky who is living in Goa. Pinky refuses to meet up or even talk and confers with her new boyfriend Dr D'Souza. Sudhakar threatens pinky that he would commit suicide, but she does not believe him. A depressed Sudhakar tries to commit suicide by hanging from the bathroom shower but fails. Bell Boy Vincent (who is in Mangal Singhs room at that moment) hears the ruckus and opens the centre door between Mangal Singh & Sudhakars room due to which all characters get to interact with each other. CHECK OUT: Love brewing between Kavin and Mandy?
Mangal Singh scared that cops might come to the room, assures Vincent that he would take care of Sudhakar and there is no need to call the cops. Assured by this promise Vincent leaves Sudhakar in the care of Mangal. Sudhakar in the meanwhile assumes that Mangal is a truly good samaritan and taking fancy for his friendship does not let Mangal go anywhere or let him do his job.
Pinky's boyfriend Dr D'Souza (a psychiatrist) comes to the hotel to counsel Sudhakar not to commit suicide, but ends up meeting Mangal & mistakes him to be Sudhakar and gives a sedative to Mangal due to which he is not able to do any work. Completely baffled by these turn of events, Mangal forces Sudhakar to call the Dr. back who now comes with Pinky and cures Mangal of his condition but not before Pinky and Sudhakar have a chat which causes more distress to the Dr.
Pinky has a major showdown with both Dr D'Souza and Sudhakar and leaves in a huff only to return and speak again to Sudhakar and convince him to go away.
During the course of the story we also visit Manu Gupta's entourage which is travelling from Bombay to Goa in a police van disguised as a Milk Van with a group of commandos in it. At each visit, we see how Manu Gupta is making their lives miserable with his silly antics.
All this while Mangal Singh who has come to Goa for the special operation is unable to do anything and undergoes several shocks of being treated multiple times by the Dr and reacting adversely to each dose of medicine while Sudhakar keeps pestering him to reach out to Pinky and help him get her back.
Manu Gupta the scamster finally reaches Goa but before he can be shot by Mangal, tremendous ruckus follows in the room where Mangal, Sudhakar, a Cop and others fight it out and literally end up dangling from the hotel while a shot is accidently fired from Mangals gun which hits Manu Gupta's ass!
Despite this hit, Manu Gupta reaches the court and gives his witness against all scamsters. Mangal Singh retires in a Ashram due to the shock of forced friendship thrust upon him. Sudhakar gets back to Pinky and lives in acrimony with their child.
