Writer Yudi (Saif Ali Khan) wrote a hit book five and a half years ago but he is still living life king-size in Los Angeles, enjoying fame and affairs, avoiding commitment, doing no work, partying with his miserably married friend Montu (Ranvir Shorey) or having conversations with his fat, bearded inner voice brother Yogi (also Saif). Suddenly, Yudi’s money runs out and his publishers dump him for hit romance novelist Aanchal (Ileana D’Cruz), visiting from Mumbai.
The only work Yudi now gets is from Bollywood single-screen superstar Armaan (Govinda) who insists he copies Hollywood movies and writes a multiplex-style romedy (romance & comedy). Meanwhile, Yudi’s dentist and once-girlfriend Vishakha (Kalki Koechlin) is pursuing him obsessively, even loading videos of him singing in the shower on her laptop, forcing Yudi and Montu to break into her home when she’s away. On top of this, Yudi’s got severe writer’s block, stopping him from finishing any work.
Running away from it all, Yudi tries to charm Aanchal but she’s commitment-averse too. However, she gradually warms up to him, escorting him to Armaan’s party, trying to help Yudi write, even agreeing to take a road trip with him to her book reading in San Francisco.
