The film features three friends Amar, Meet and Prem who always want fun (Masti). The film begins with the title song where the three friends get married to Sapna, Rekha and Nisha. They are unhappy with their marriage life because of their mother-in-law, brother-in-law and sister-in-law respectively. Amar's mother-in-law wants her late husband to be reborn and on the order of a fraud Baba (honorific). She has stopped her daughter from having any physical relations with Amar for over 6 months to achieve the rebirth of her late husband. Meet's wife is a twin and whenever he tries to go near his wife, it turns on his brother-in-law (who is a bodybuilder). The connection between the two twin causes great problems like Meet's wife beating him up unintentionally when her brother is beating up some goon. Prem's sister-in-law is very attractive yet very silly, she comes to live with them and wants to sleep with her elder sister, forcing Prem to sleep on the couch away from his wife.
