Writer Yudi (
Saif Ali Khan) wrote a hit book five and a half years ago and 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 copy Hollywood films and write a multiplex-style romantic 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, and even agreeing to take a road trip with him to her book reading in San Francisco. Eventually reaching
San Francisco, the couple is forced to share a hotel room – and after agreeing to keep it simple and commitment-free, they end up making love. Their relationship grows funnier – on Aanchal's last night in LA, they argue over dinner, Yudi throws her phone into a vase while she douses him with water – but neither expresses anything more than a sense of light fun. It's only when Yudi's ex-girlfriend Divya (
Priety Zinta), having argued with her husband and visiting Yudi with her kids, tells him he loves Aanchal that he admits it to himself. Yudi then races Aanchal's taxi to the airport in a hilarious scene and tells her his feelings, but she expresses her wish to remain friends with him. As she leaves, Yudi sinks into depression, and then starts to write. Along the way, Vishakha gets engaged to a panic-stricken Yudi by falsely claiming she's pregnant – but then breaks it off, saying she doesn't want him to marry her out of pity. Armaan, who has meanwhile gotten himself cosmetic surgery and six-pack abs in LA, is impressed with the 'kick-ass' script Yudi presents him. However, for the script's ending, Yudi goes to Mumbai and sees Aanchal where he tells her they can take it one day at a time – and perhaps live their whole lives together like that. Aanchal smiles and the happy ending begins. ==Cast==
