Sidharth Mehra (Ranbir Kapoor) is a Bombay twenty-something who coasted through college and continues to lounge his way through post-university life. Sid may be slothful, but he always musters up the energy for his friends, including the new arrival in his life, pretty Aisha Bannerjee (Konkona Sen Sharma). While Sid is content with his lack of direction, Aisha is driven to become a writer. With Aisha in his life, will Sid grow tired of a life of parties and join Bombay's workforce?
