Sanjay (Uday Chopra) and Ria (Bipasha Basu) are close friends who share the same apartment. Although there is some infatuation between them, they believe that a boy and a girl can stay together as friends, without love coming into the picture. But Sanjay is a whimsical guy who doesn’t trust his own feelings.

Things go topsy-turvy for Sanjay after he receives a call from his childhood friend Anjali (Sanjana), who invites him to her marriage. Suddenly he is unsure of his feelings for Ria. Thanks to a little prodding from Ria, it suddenly dawns on Sanjay that he has been in love with Anjali all his life.

This realization dawns on him just in the nick of time. Being a go-getter by nature, Sanjay packs his bags and sets off to Anjali’s house with the noble (or the contrary) mission of breaking up her marriage.

The film then strays into “Dilwale Dulhania Le Jayenge” mode with Sanju doing everything to win the love and affection of Anjali’s family comprising pampering mom-dad (Neena Kulkarni and Alok Nath), a loving grandmother (Dina Pathak), a Vastu-Shastra freak aunt (Bindu) and a pessimist uncle (Saurabh Shukla).

Anjali’s groom-to-be is handsome and suave Rohit (Jimmy Shergill). A doctor by profession, Rohit is a good-hearted fellow who has the makings of an ideal husband.

Sanjay hatches a plan to tarnish Rohit’s reputation in Anjali’s eyes. He invites Rohit to a party where he makes his small-time friend (Shamita Shetty) flirt with Rohit. When Anjali finds her hubby-to-be cuddling in the arms of a bimbo, all her hopes are shattered.

Rohit too is no bum, and soon realizes that Sanjay is bent upon deliberately belittling him before Anjali and her family. He confronts Sanjay. Ultimately the duo decides to leave the final decision to choose one of them to Anjali. Now the question is, whom will Anjali choose?
