Siddharth (Farhan Akhtar) and Trisha (Vidya Balan) are a happily married couple until Trisha gets pregnant and things start getting complicated. Sid is not ready for a baby as he is just a struggling music composer, yet lies to Trisha. On his friends' advice, Sid starts reading pregnancy books and following Trisha's daily routine. Sid makes a desperate attempt to behave like a family man but fails, as on one occasion he takes his baby for a walk but forgets her in the market. Frustrated, Sid asks for help from Trisha's brother-in-law Ranveer (Ram Kapoor), who is a typical family man. Ranveer reveals to him that when he gets frustrated, he makes a business trip excuse and stays in a hotel room to enjoy his life as a bachelor. Sid takes on his idea and starts staying in a hotel, with the excuse of working overnight in studio.
