Harpreet "Happy" Kaur (Diana Penty) is supposed to marry Corporator Daman Singh Bagga (Jimmy Shergill) in Amritsar, India, but has planned to elope with her musician boyfriend Guddu (Ali Fazal). She inadvertently finds herself aboard a lorry destined for Lahore; she is trapped inside a fruit basket that is delivered to the house of Bilal Ahmed (Abhay Deol), the ex-local governor's son. Meanwhile, in Amritsar, Guddu is taken hostage by Bagga. After fleeing Bilal's house, Happy creates a ruckus at a local marketplace and is arrested by police officer Usman Afridi (Piyush Mishra). The officer informs Bilal, who decides to arrange for Happy's deportation. Unwilling to return to Amritsar, Happy blackmails Bilal into helping her using a contrived story about her being abducted by Bilal and his father. Bilal is then confronted by his fiancée Zoya (Momal Sheikh), who initially suspects him of having an affair with Happy. Zoya later suggests bringing Guddu to Lahore, have him marry Happy there, and deport them together. Bilal begrudgingly agrees to help Happy but has difficulty keeping her a secret from his father and struggles to keep Happy reined in. Bilal finds himself attracted to Happy, who develops a close friendship with him and Zoya. When Bilal's father travels to China for two weeks, he decides to go to India with Afridi to rescue Guddu. They pose as members of a Lahore-based music company and persuade Bagga they want Guddu to perform for their production in Lahore. Bagga realises their subterfuge and helplessly watches them board a bus to Lahore from Attari. He hires goons who abduct Happy from Bilal's house and sets off to Lahore along with Happy's father. Afridi arrests Bagga upon arrival and Happy's father escapes. Afridi rescues Happy, who re-unites with Guddu. Completely smitten with Happy, Bilal begins to avoid Zoya but reconciles with her later. Happy's father, in his desperate attempts to find his daughter, is mistaken for an Indian spy who is planning to kill Bilal's father. Bilal arranges for Happy's marriage to Guddu at a mass wedding event. Having escaped prison, Bagga also arrives at the mass wedding disguised as a groom. The event turns chaotic when Happy's father makes a frenzied attempt to get the governor's attention using a police officer's gun. Happy marries Guddu and they head to the airport chased by Happy's father, Bilal and Zoya, and Bagga and his goons who lose track of the group. Before boarding the flight to Amritsar, Happy seeks validation from her father, who obliges. She embraces Zoya and Bilal and departs. In a post-credits scene, Bagga seeks support for his election campaign at a public rally with Happy and Guddu in attendance; he declares himself the couple's saviour. Onlookers react with complete bafflement, much to the duo's amusement.
