(Released: May 8, 2015)
The film starts off with a day in the life of the Delhi based Piku (Deepika Padukone), whose world revolves around her architectural office, her colleague Sayyed Afroze (Jishu Sengupta) and her father ever-so-doting father Bhaskhor Banerjee (Amitabh Bachchan). Life is absolutely monotonous for her. While her day starts off with her office and ends with her ever-worried-about-constipation father Bhaskhor. Despite all her efforts to brainwash him off the same, he refuses to budge. That's why she compromises with the existing situation, which also means that she has to cancel a lunch date in order to attend to her 'mentally constipated' father's constant SOS. Just when life is moving in a monotonous manner for the Banerjee family, a sudden decision to travel to Kolkata springs up. Because Bhaskhor rules out the possibility of travelling by air or train citing his constipated problems, the family decides to go on a road trip to Kolkata. One the other hand, due to lack of 'availability' of any driver, the owner of a rental taxi service Rana Chaudhary (Irrfan Khan) decides to drive the car himself. It is during this trip that Piku and her father realize a few bitter facts about life and about each other, courtesy, Rana, who doesn't believe in mincing words when it comes to calling a spade a spade. It is during this journey that a romantic tension develops between Piku and Rana. But when they reach Kolkata, a tragedy strikes the Banerjee household, which, not only changes the entire course of Piku's life, but also brings the entire Banerjee household to a standstill. What is this tragedy that strikes them, will Piku ever be able to find love and does Bhaskhor ultimately find a solution to his constipation is what forms the rest of the film.
