Mumbai-based collegian-slackers Sid(Arshad Warsi), John(Ashish Chodhry) and Amit(Yash Tonk) do graduate after several years, are unable to find employment, and form a Punjabi Rock Band with the help of a gangster, Munnabhai(Ashish Vidhyarthi). When John's attempts to woo fellow-collegian, Natasha (Arti Chabria), go in vain, his buddies assist him in pursuing a beauty named Sheetal(Udita Goswami), and John falls head-over-heels in love with her. He introduces her to his wealthy father, Albert (Adi Irani), who would prefer that he take over their business - a toy factory - and upon being refused, asks him to leave. Sid and Amit soon find that Sheetal, an expert in martial-arts, is very possessive, does not approve of their lifestyle, and prevents John from seeing them. Watch what happens when John finds out that Sheetal has been abducted, believed to be dead, and the culprits are none other than Sid and Amit.
