Prem (Ranbir Kapoor) is a high school dropout who hangs around with his friends at his Happy Club. The happy-go-lucky young man has no job and takes no responsibilities much to the disgust of his father Shankar Sharma (Darshan Jariwala). He is adored by his mother Shalini (Smita Jaykar). Prem and his friends do their best to bring lost lovers together. When Jenny (Katrina Kaif) moves into the neighbourhood, Prem falls for her at first sight. She befriends him despite the differences in their backgrounds – she is Christian while he is a Hindu Brahmin; she is well-qualified while he is 9th fail and so on. But very soon, Prem is heartbroken when he finds out that Jenny loves someone else. But being the Happy Club President that he is, he goes on to set her love story straight.
