Nikhil (Sidharth Malhotra) is a struggling businessman, who thinks he loves Karishma (Adah Sharma), an actress. Nikhil is characterized as a person who believes that once you are committed to a girl, there should be no straying. Karishma asks Nikhil to arrange ?50 million (US$750,000) before marriage, which is 7 days later, to earn a contract.

Nikhil meets Meeta (Parineeti Chopra), Karishma's younger sister, with whom he had a brief encounter 7 years ago. Meeta, who is an IITian in Chemical Engineering and PhD., is a super-intelligent geek with unusual behaviour and habits, who ran away 7 years ago to China after stealing money from her own father, leading to his heart attack. Now, just a week before Nikhil and Karishma's wedding, Meeta has turned up to meet her father, but Karishma is scared that her sister's sudden appearance might ruin their wedding. Hence, Karishma assigns Nikhil to keep Meeta away from her father (Manoj Joshi).

Meeta has returned with an intention to steal again but her involvement with Nikhil during the next 7 days diverts her attention. During these 7 days, with many personal and social activities, Nikhil and Meeta fall in love but Nikhil backs off as he doesn't want to betray Karishma. He comes to know that for her research, Meeta has taken a heavy loan of ?100 million (US$1.5 million) from a Chinese investor by forging her father's signature. The deadline for payback is over and an extension of three days was given, during which she has to steal money from her father's account to save him from the investor's goons. Nikhil helps Meeta to hack her father's account but advises her to apologize to her family. Meeta reunites with her family and Nikhil realizes he is marrying the wrong girl.

Meeta is unable to gather the courage to steal her father's money and tells her father the truth. Her father forgives her and provides her with the money. Nikhil later tells Meeta on the phone that he should have gone with her to Goa when she asked him to come with her 7 years ago. Meeta tells him that it is not too late for them to run away.

When Nikhil comes to Meeta's house to run away with her, he sees Karishma with her family and returns home, realizing the complications. Nikhil later scolds Meeta for being so ready to run away and says that he cannot torture Karishma even though Karishma has emotionally tortured him throughout their relationship. Nikhil leaves Meeta and tells her to go away from here. Later that night Nikhil receives the call of his investor Mr. Adlani and gets the news that he liked his plan and is ready to invest in his plan.

On the wedding day, Meeta leaves her house without informing anyone except her father, leaving her mobile phone inside Karishma's room. Nikhil tries to call her and sends many texts, which go unanswered. On reaching the mandap Meeta's father informed him that she has already left for china. Karishma finds Meeta's phone in her room, reads the messages, and realizes she has lost Nikhil. During the wedding she asks Nikhil to leave the wedding, her decision is supported by her father. Meeta on the airport cries hard and tries to end her life but gives up that decision and goes back to wedding. The two reunite and express their love.

The movie ends with Nikhil and Meeta at the airport, scheduled to travel to Germany. Meeta tells him that there is another problem waiting for them.

Development

Karan Johar's production house Dharma Productions is financing this film along with Phantom Productions, which is run by four filmmakers - Anurag Kashyap, Vikramaditya Motwane, Vikas Bahl and Madhu Mantena.

Casting

Anurag Kashyap, who is very excited about this project, said, "The story works with fresh faces, but requires a high level of chemistry and maturity in the performances. After spending months shortlisting various actors, we finalised Sidharth and Parineeti." Reportedly, Adah Sharma is playing the second female lead in the movie and the sister of the film's female protagonist. To capture the seven-year period covered in the film, Vinil Matthew wanted Parineeti Chopra to have different hairstyles.

Filming

Filming began on 18 April 2013. On talking about the director Vinil Mathew, Sidharth Malhotra, who would be cast as a middle class working man in the film, said, "It didn't feel like the first day of shoot because he is so sorted and knows exactly what he wants. He made us rehearse a lot during a two-month workshop before shooting began". In an Interview Sidharth says, he plays a character who is stressed out, lost and sentimental. He meets a girl who is a bit cracked. Actress Parineeti Chopra reported that her character was a quite difficult one. It is the first collaboration for both the protagonists with each other, but however, none complained and instead, both were praising each other to be energetic and tireless. The fact that actress Adah Sharma was also involved in the cast as one of the lead characters was supposed to be kept a secret as the producers wanted to make an official announcement about it. But it was later revealed as Adah was seen shooting for the film at the Bandra Bandstand Promenade.
