In the city of Lucknow, Gattu (Rajkummar Rao), a jobless Union Public Service Commission aspirant has fallen in love with Binny (Shruti Haasan), a girl who lives in his neighbourhood and is well aware of ''Gattu'''s feelings for her but doesn't pay much attention to him because she finds him to be a coward. Gattu's desire for a marital bond with ''Binny'' puts him in a situation where he has to not just face off with a family of criminals who want to make ''Binny'' their Daughter-in-Law at any cost, but also gather the courage to convince his own parents and neighbours that all boys and girls living in the same neighbourhood are not brothers and sisters.
