Director: Vikram Bhatt
Karan (Shahid Kapoor) is a shy and nerdy canteen boy and college student, running a café with his friend Murugan (Johnny Lever), and Tanya (Rimi Sen) is a student in the same college. She is the most popular girl on campus. Karan is in love with Tanya but is too shy to tell her. After he musters some courage and rescues her step-brother from some goons, he catches her attention and is eventually able to invite her to a fake birthday party. On her way there, Tanya witnesses the murder of a scientist, Khurana (Om Puri) by his evil twin brother, the underworld don Mehboob, and as a result is forced to flee the country to save her own life, since the law had been bought out by the very same killers. The scientist had stored a secret code in a stuffed toy, a parrot, now being sought by Mehboob, and Khurana was able to hide the toy in Tanya’s car before being killed. Unawares, Tanya leaves the toy at home before fleeing the country, and the toy is later picked up by Karan, ignorant of Tanya’s fate.
Three years later, still in love with Tanya, but depressed by her sudden and complete disappearance, Karan stumbles across old schoolmates of hers at a café, and learns from them that she had been living in Dubai all this time. Karan coaxes Murugan to help him track down Tanya in Dubai. They enlist the aid of a local hustler and bounty hunter, Rocky (Akshay Kumar).
Rocky travels to Dubai, where his friend Babloo (Vijay Raaz) has already tracked down Tanya, who has become Natasha, a successful singer and performer. Rocky and Babloo stakeout Natasha’s villa to make sure they are on the right track, but as soon as Rocky spots Natasha, it’s love at first sight. While he has Natasha under surveillance, Karan and Murugan arrive at the Dubai airport from India. Faced with a potential competitor to woo Natasha, Rocky attempts to eliminate Karan from the picture by lying to him about Tanya. He says that Tanya had taken up drinking and smoking, had had two husbands, six children and also an affair with a gangster, with whom she had a further illegitimate child. He further lies that Tanya had been left wheelchair bound after a drunk driving accident. Karan is heartbroken to hear all this, and decides to go back to Mumbai. He is about to board his flight, when at the last moment, he spots a picture of Tanya as Natasha on a club advertisement printed across an airport Taxi. He is overjoyed, and assumes that Rocky made a mistake, not being aware that Rocky is in fact trying to deceive him.
Things are about to get more complicated, since not only has Rocky to contend with Karan, there are two other people already in her life, trying to catch her in their web of deceit. Local plumber, Sanju Malvani (Sunil Shetty) has been currying favours for Natasha by pretending to be a paraplegic on crutches. Every time Natasha meets someone she likes, Sanju eliminates the competitor using a unique trick. He edits and prints out a fake newspaper featuring an article showing that person as a crook, and comes over to Natasha and shares “the news” with her while acting all shocked himself, thus earning her admiration. On the other hand, there is Tanya’s physically disabled live-in friend Tommy (Paresh Rawal), who also has a soft spot for her. Having heard of the death of Tanya’s disabled brother a year ago, Tommy has since faked being run over in a car accident and now acts like he himself is disabled and mentally challenged, thus managing to stay close to Natasha by seamlessly filling in the void left behind by her deceased brother.
Nonetheless, Rocky begins his attempted seduction of Natasha. Having wired the villa, and thus overheard what Natasha craves in a man, Rocky shows up at the local shopping mall, pretending to be an architect. Natasha, who is shopping at the mall, is ambushed in the parking lot by a bunch of thugs (who it later transpires are simply mugs hired by Rocky himself). Rocky intervenes, and after seemingly beating the living daylights out of the supposed thugs (the scene is similar to Jean-Claude Van Damme’s introductory action sequence from Hard Target (1993)), introduces himself to Natasha, and proceeds to show himself off as a charming professional with a heart of gold. Somewhat awed, Natasha offers Rocky an invitation for tea later in the evening, which he accepts.
When Rocky arrives at her villa later in the evening, he is confronted by several obstacles, Natasha’s sister Sweety (Supriya Pilgaonkar), the jealous Tommy and the family’s pet dog. Rocky is easily able to charm Sweety, but has to drug the dog, who dies due to an overdose while the sisters are making Rocky a drink in the kitchen. Crisis is avoided when Rocky is able to revive the dog by electrocution using wiring from a lamp in the living room. The parties then quickly depart to the grand opening of Natasha’s latest album at a social event, where Rocky now comes face to face with Sanju, who puts Rocky on the spot right away, as he himself is pretending to be an architect!
With Natasha and company under surveillance, Rocky now intercepts Sanju trying to discredit him at Natasha’s home. Later, when the shocked Natasha confronts Rocky about him being an alleged impostor, Rocky is able to fast-talk his way out of the situation and convince the gullible Natasha that he is indeed not an architect, but a captain on a ship, something his mother does not approve of, thus the ruse. Tommy, however behaves in a somewhat jealous manner and puts Rocky in a confusing situation, involving him jumping on Rocky’s back and then accusing the latter of having twisted and bitten his arm. A food bill from a bar drops out of Tommy’s pocket during his supposed accusation. This arouses Rocky’s suspicions about his supposed “condition”.
The next day using that food bill, Rocky and Babloo track down Tommy at a local disco where, unaware that he is being followed, Tommy shows up every week, for a little fun and dance away from his daily existence as a fake disabled victim. Rocky confronts Tommy while he is on the disco floor and threatens to expose him in front of Natasha. At the end, Rocky lets Tommy go, on the condition that the latter will no longer attempt to get in his way of seducing Natasha.
The scene now shifts to the harbour, where Rocky has invited Natasha over for a cruise. While he is coddling her on the harbour front, Natasha spots Karan and Murugan sitting at the grounds. Unaware that Karan is in Dubai searching for her, she is overjoyed to see an old friend from her past. She introduces Karan to Rocky, unaware that they know each other quite well already! Karan, however, seeing Rocky and Natasha all smiles and happy, simply wants to leave them alone out of his love for Tanya. He just wants her to be happy, even if it is with Rocky and not himself, much to Murugan’s frustration. While he tries to leave the scene, pretending that he and Murugan have a flight to catch, Natasha convinces Karan to stay one more night in Dubai, and come over for dinner later in the day.
Sanju shows up later at the party, and pulls Natasha aside to reveal his latest newspaper creation, showing Rocky as an international crook, murderer and serial killer wanted by many crime agencies the world over, whose M.O, as Sanju explains is to trap and seduce innocent girls like Natasha and then destroy their lives. Rocky overhears the conversation and while Natasha is occupied elsewhere, chases Sanju outside in the club parking lot. Sanju drops the pre tense of being crippled, throws his crutches on the ground, and runs for dear life. Later, Rocky, Sanju and Tommy are seen sitting in a bar nearby after a confrontation, exposing each other as fraudsters and having a drink together, cursing their luck at the emergence of Karan as the new love in Natasha’a life.
With Rocky having bugged Natasha again, the trio now listen to Natasha’s views about them and find out, in a hilarious manner, that all is not what it seems, since she views Sanju as a brother like figure, Tommy as something similar to her deceased brother, and Rocky as a fraud and murderer. They then go to Natasha’s house, where she is having coffee with Karan. Rocky uses a gun to shoot some specially medicated pills into the drawing room to be consumed by the dog. One of them is consumed by the dog, but the other is consumed by Sweety. The effects are hilarious as Sweety suddenly becomes hyperactive and so does the dog. Confusion ensues as the dog attacks Karan and he ends up throwing it out the window.
The next day, Karan goes to Natasha’s house to propose to her and finds that she has been sent an anonymous letter, informing her that he indeed had hired Rocky to follow her. In a spate of anger, she sends him out of the house. Later, when he goes to Rocky’s house to confront him about this, he finds Sanju and Tommy there as well, who also reveal themselves to have been conning Natasha. Further, Sanju reveals that he had written the anonymous letter to Natasha and goes on to reveal his trick with the newspapers, disgusting Karan. Meanwhile, Mehboob and his family, including Sunny, (his illegitimate son, who has also been obsessed with Tanya since college) arrive at Natasha’s house and interrogate her about the stuffed toy. Realising that his father had used his obsession to track down Natasha, Sunny turns on his father and kidnaps her. Sweety informs Sanju about this and he along with Rocky, Karan and Tommy follow them after having gotten directions from Murugan, who happened to see them from a taxi. The chase takes them to the middle of a desert, where after some confusion, it is revealed that Khurana had stored the code of a vault in the stuffed toy. The vault had carried a secret solution, two drops of which could decrease a person’s age by 25 years. The night Khurana had died, he had found that his brother wanted to use the formula for his own consumption and had tried to escape in Natasha’s car as she had been passing by. He had slipped the toy into a package, a birthday present she had been carrying for Karan’s fake birthday dinner, thus explaining how he had the toy. Khurana used the toy to counteract his forgetfulness. Natasha sent him out of the car at first, but, undergoing a change of heart, had gone back later just in time to witness Mehboob’s son Baljeet kill Khurana.
Rocky intervenes and cleverly destroys the toy after having it speak the code into Natasha’s ear, making sure she cannot be killed, the code being in her mind now. A gunfight ensues, during which Natasha discovers Tommy and Sanju’s deceit, much to her shock and disgust. After the commotion, Baljeet, wanting the solution all for himself, to sell to a Chinese buyer and make millions, kidnaps Natasha. Rocky and Sanju follow them on bikes and finally manage to catch up with them. After beating up all the men, they take Natasha to her house where a further argument ensues as to who should be more worthy of Natasha. The argument ends when Karan arrives with Raj Sinha (Aftab Shivdasani) and tells Natasha about Sanju’s newspaper scams (which the latter confesses), one of which had exposed Raj as a drug dealer and addict earlier. Raj and Natasha are reunited. Wishing them luck, Karan leaves in sadness after the others are left cursing.
Natasha realises her love for Karan and stops him as he is leaving, saying that she and Raj had had no future ever since their earlier break up. She then accepts and reciprocates his love and they finally unite. This tearful union is once again being witnessed by a grumbling Rocky, Sanju and Tommy along with Sunny. Rocky impatiently tells them to stop cursing and asks them to admit to the fact that they were never worthy enough for her. He then turns to Babloo and suggests, in a whisper, that they try to find out where Karan and Tanya are going for their honeymoon and they eagerly put on a pair of earphones. In the last frame, the camera pans to Tanya and Karan walking away towards the sunset, hand in hand.
At the end, the narrator says that after all the effort he had undertaken to acquire the solution, Mehboob had become too overexcited and had consumed the whole quantity instead of two drops. He had ended up becoming a baby and Sunny unwittingly became his father. The film ends as the narrator requests the audience not to forget him.
