Raj Oberoi (Govinda), the pampered grandson of Krishna Oberoi (Shammi Kapoor), a big industrialist whose property his two notorious sons Dilip (Shakti Kapoor) and Ashish (Rana Jung Bahadur) want to grab. Raj loses his mental balance in an accident and takes on the behavioral patterns of a child. Having lost a touch of his sanity Raj keeps playing pranks on Murari (Kadar Khan) who has been left in his care by his doting grandfather. Raj's uncles and his cousin Vicky (Monish Behl) – who always stays in an inebriated state – see Raj's mental illness as the appropriate opportunity to take over the entire wealth of Krishna Oberoi. To this end they all gang up and sideline Raj by sending him off to Shimla, which is Murari's hometown. In Raj's absence the scheming relatives get rid of old Krishna Oberoi. Meanwhile, Raj too goes missing after being struck by an avalanche in Shimla and the entire property is taken over by the rest of the Oberoi family. Just when the baddies think that all is hunky dory, there enters into picture a mysterious Banne Khan (Govinda), a look alike of Raj.
