When an unwilling Prem is forced by his overbearing father (Sanjay Mishra) into a marriage with Sandhya (Bhumi Pednekar), who is not only over sized but over educated too, Prem finds himself in a fix. He is smitten by Kumar Sanu's voice and listens to his songs on loop. Prem gets shivers with the mention of English language and so hence he prefers to leave his education and work for his father's recording shop. Prem (Ayushmann Khurrana) is a Haridwar bred middle class guy who is safe to be termed as a man-child. Coming from a patriarchal cognitive set-up, she doesn't fit the quintessential idea of beautiful. Having completed her degree in B.Ed and waiting for a teaching job, the most visible thing about her is her weight. His father is keen to get him married and the family goes to a local temple to meet Sandhya (Bhumi Pednekar).

Prem owns a cassette shop in the local market. Set in Haridwar, 1990s, the film captures the nascent feel of the town. Prem Prakash Tiwari (Ayushmann Khurrana) listening to Kumar Sanu is the film's opening shot. Then their Hatred for each other turns into love eventually. The relationship between the boy and the girl becomes uglier. A marriage takes place against the will of the boy. A beautiful love story of a under-educated boy and a over-weighted girl.
