The film opens with adult Ved (Ranbir Kapoor) and Tara (Deepika Padukone) are in a spectacle which shows of the monotonous life of a person in the corporate world. A scene in the spectacle turns to a flashback in Shimla where young Ved (played by Yash Sehgal) and his father (played by Javed Sheikh) return to home from school. As a child, Ved is fascinated by the stories narrated by a road side story teller (played by Piyush Mishra) who keeps mixing up his characters.
Present day, the film moves to Corsica where Tara meets adult Ved. However, they have a verbal pact to keep their real identities undisclosed. They explore the island together. They make conversations as "Don" and "Mona Darling". Running out of money, they put up a spectacle at an expensive restaurant. As Tara is set to leave for India, she is lovelorn despite a romantic friendship with Ved. The story flashes back to young Ved who questions the story-teller about the reason for happy times ending up quickly.
Tara returns to Kolkata in India and her routine life is shown through the song "Heer To Badi Sad Hai". Tara's father (played by Nikhil Bhagat) hands over his tea business to Tara so that she starts a line of tea boutiques, taking the company ahead. She is off to Delhi for work and four years have passed. Once upon a day, Tara surprisingly meets the adult Ved, who is now a product manager. They reveal their original identities. She makes an attempt to move ahead of the unrequited love by fixing a dinner with Ved at a Japanese restaurant. She expects him to talk like the days in Corsica but Ved talks about business. She calls Ved up home to be intimate. Ved leaves for his home and next morning Ved wakes up on time, completes the morning chores, wipes the car, ignores the eunuch on the way, lets a female colleague into the lift all this happens on his way to the office. He fixes a plan for meeting Tara again in the evening. The evening to evening incidents repeat monotonically.
It is Ved's birthday when he proposes Tara but she is unhappy with a changed Ved after his arrival from Corsica. She declines the proposal. Ved leaves for his home by an auto-rickshaw driver (played by Ishteyak Khan) who narrates how his dreams of becoming a singer were crushed.
The film goes in flashback, scene in Shimla, where Ved tells his weakness in Mathematics and doesn't wish to do engineering. His Dad narrates him that he had to give up his interest for flute playing to support his family after they moved to Shimla from Lahore post the Partition of India.
The film comes back to present day Delhi where he starts telling his life story to some local people in search of answers and certain flashback scenes of Shimla are shown where Ved leaves Shimla to pursue engineering. Ved, due to his split personality ends up upsetting his boss by non-sensical business meeting performance. The story returns to Tara's door where Ved puts up his frustration at Tara. Tara promises him to help him come out of his divergent behaviors but he leaves.
The next day, Ved continues his office routine with a change, now giving the diamond ring to the eunuch. Ved comes back to Shimla and revealing his joblessness. After a quarrel with his father, Ved gains introspection from a reflection in the mirror where he realizes that to complete his own story, he needs to meet the same story-teller. The story-teller criticizes Ved's regression, compelling him to complete his own story. Ved narrates his life story to his family members. Moved by this, his father lets Ved pursue his interest.
Ved returns to Delhi and takes the diamond ring back from the eunuch. Tara, after finishing a business meeting at Oracle in Tokyo, she heads for refreshment where she finds a note titled "Don Returns". Perplexed about Ved's presence, she moves around the office campus where Ved draws her attention as the disguised "Don" in Corsica.
The film goes into a flashback and shows scenes from Shimla of a free spirited-young Ved, a college going Ved and an adult Ved. The film returns to present day (first scene of the film) where Ved and Tara complete the process of putting up a show on stage (in continuation of the opening scene of the film) through the spectacle which is the complete story of the film on presented on the stage.
