Gattu is a 23 year old middle class boy from Lucknow who is in love with his neighborhood crush Binny since his childhood days. However, his family members believe that all girls of the area are like one's sister and hence, Binny too has been accorded Gattu's sister since the day they were kids. Gattu, though, doesn't believe in this definition and Gattu works to capture Binny's heart and the approval of his community.
