Sid thrives around his two best friends, Rishi [Namit Das] and Laxmi [Shikha Talsania], very rarely communicates with his mother Sarita [Supriya Pathak] and takes his father Ram Mehra [Anupam Kher] and all his hard-earned wealth for granted. Despite all these traits, Sid is an honest boy; sweet, funny and above all, a good friend. Aisha Bannerjee [Konkona Sen Sharma], an aspiring writer from Kolkata, learns this soon enough when her path crosses with Sids on her first day in Mumbai. Ambitious, well-read and driven, Aisha has come to Mumbai to realize her dreams as a writer. Despite their contrasting personalities, Sid becomes Aishas first friend in the city. As Aisha sets up her life in Mumbai, with the help of Sid and his gang, Sid allows for time to fly by over long drives, parties that stretch well into dawn, and endless hours doing absolutely nothing. But a series of circumstances and events compel him to take stock of his life and take a hard look at himself.
