Sidharth “Sid” Mehra (Ranbir Kapoor) is the carefree son of wealthy businessman Ram Mehra (Anupam Kher) and Sarita (Supriya Pathak) in Mumbai. Depicted as a spoiled slacker, Sid shows little concern for his plans after college, barely studying for tests and having no interest in working for his father. At the farewell party after the final exams, he meets Aisha (Konkona Sen Sharma), an aspiring writer recently moved away from her hometown of Calcutta, who happens to be one of his college mate’s roommate.
