Aditya "Adi" Gunjal comes to Mumbai to work for a gaming company owned by Prahlad Kakkar, aspiring to achieve big in the United States as a video game developer. At Mumbai railway station he spots a girl on the adjacent platform trying to jump in front of an approaching train. A horrified Adi gives her a shout. The girl then disappears. Adi moves into the house of Gopi Srivastava, his elder brother's senior, a strict retired High Court judge living with his wife Charu, a renowned Hindustani classical singer who suffers from a stage two Alzheimer. On his first day at work, he is encouraged by his friend Bantee to pitch the idea of his game 'Mumbai 2.0'. Adi impresses his boss and gets a deadline of five months to prepare a prototype to be sent to Los Angeles for a competition. Later at his friend Jenny's wedding, Adi spots the girl from station. The girl introduces herself as Tara. They make acquaintance. Tara is planning to pursue her architectural studies in Paris and Adi dreams of becoming a big shot like Mark Zuckerberg. Adi and Tara strike a chord over their mutual presumptions on dysfunctionality of the institution of marriage. Tara also reveals that her antic at the railway station was a ploy to get rid of her ex-boyfriend who desired to marry her. Subsequently, they hang out, exploring the city. The next day, Adi pursues Tara to Ahmedabad on her work trip. Tara takes Adi to Sabarmati Ashram which she used to visit with her father, as a kid. She shares with him that her decision to never marry was incited by her parent's broken marriage. Finally they approach Gopi and Charu, with their wish to live-in with each other before they go their separate ways for their respective careers, to which Gopi strongly disagrees but then has to give in as Tara impresses Charu with classical singing. Adi's family plans to give Adi a surprise visit and his sister-in-law figures out them living-in together, to which his brother would adamantly be opposed to. She asks Tara to ponder on their future, when Tara at some point would have to pick between her love and her career. Tara and Adi continue living happily, getting a thrill out of their mutual endearing camaraderie and growing affinity and attachment. Tara's admission in the institute at Paris gets approved. Tara informs Gopi and also confides in him that it might now be hard for her to leave Adi and go so far away. The next day Tara goes to Jaipur for a work trip, and Adi starts to miss her profoundly. Adi gets summoned to Kanpur by Tara's affluent mother, who wishes to know his intentions for her daughter. And so on her return from Jaipur, Tara finds Adi missing and searches for him miserably, realising living without him would be forlorn. Soon upon seeing the love and patience Gopi has for his ailing wife, who one day goes missing as she bewilderedly forgets the way to her own house and is found by Tara and Adi sitting on a temple's platform in heavy rain, they begin to understand the importance of each other's presence in their life. Tara's mother visits Gunjals to discuss a marriage, infuriating Tara. Later in the day, Adi's game 'Mumbai 2.0' gets selected for the competition in LA and hence he soon is to leave for the US. He confides in Jenny that it'd be hard for him to leave Tara. Tara too seems visibly vexed. The next day, Adi and Tara make a pact to enjoy themselves to the fullest for the next 10 days after which they would eventually go their separate ways. One day, Charu goes missing again. While looking for her, they start bickering about their relationship and after finding her and bringing her home back to her husband, Adi finally proposes marriage to Tara before they leave for their respective destinations. They get married in Gopi's house among close friends and family. Post marriage, both continue to accomplish their own dreams, one in Paris, another in Los Angeles, keeping in touch and waiting for the day they can be together again.

Reception
Bollywood Hungama rated the film 2.5 out of 5 stars, stating that it is "a decent love story which works only in parts mainly because of the chemistry between Aditya Roy Kapur and Shraddha Kapoor." Writing for Hindustan Times, Anupama Chopra rated the film 2 out of 5, commenting, "This is just a pointless film, because an exact frame-for-frame version already exists in Tamil", referring to O Kadhal Kanmani, directed by Mani Ratnam. Chopra described Kapur and Kapoor as "too lightweight" to bring a comparable depth to the characters that the original actors did.
