Set in Paris, Befikre begins with a nasty fight between Dharam (Ranveer Singh) and Shyra (Vaani Kapoor) which leads to a sudden break-up in the opening scene; and Shyra packs her bag and leaves Dharam. She decides to go to her parent’s house and asks them to let her in without asking any questions about her ex-boyfriend, Dharam. Dharam hails from Karol Bagh, New Delhi, and is a stand-up comedian working in his friend, Mehra’s (Aru Krishansh Verma) doomed restaurant where he mocks about people being in relationships and the single bachelors.
The film travels back in time when Dharam came to the French capital in search of work and adventure. To his surprise, he shares his room with a girl who is a lesbian. Mehra takes him to a party where he hooks-up with the fun-loving Shyra, a tourist guide, who is an Indian by origin and French by nature. Instantly, they dance and get intimate with each other. The series of non-stop kisses start hereafter. Dharam asks Shyra out on a date when she dares him to slap a police officer. Thereafter, they keep giving crazy dares to each other throughout the movie.
Again at the present time, Dharam mocks about his broken-up relationship in the same joint. They keep meeting each other accidentally showing that they still haven’t got over each other. In yet another flashback, they both decide to stay in a live-in relationship and Dharam meets Shyra’s parents who are chefs in their own restaurant. After many misunderstandings and fights, Shyra moves out and shifts with her family. They celebrate their breakup anniversary in the famous Love Padlock Bridge, Paris and swears never to fall in love with each other. Although, they are dating other people, but still they remain good friends until one day when they both get into a heated discussion and become rivals. Only when they are getting married to different people, they realize that they still are tied to each other emotionally. They do a face-off dance in the ‘Sangeet ceremony’ which eventually leads them back as friends and they surprise everyone with their impeccable chemistry in the dance. Dharam secretly tells Shyra that he is not ready for marriage and also wants to stop it. During the conversation, both start developing a love for each other.
On the wedding day, Dharam, however, manages to stop the wedding and tells Shyra that he truly loves and cannot be a friend of her anymore. Eventually, Dharam and Shyra run away from their wedding ceremony.
The film ends with the marriage of Dharam and Shyra.
