Hasmukh Rai (Kader Khan) has a problem. As a matter of fact, two problems — his two sons: Munnu (Chunky Pandey) and Bunnu (Govinda Ahuja). The brothers are notorious slackers up to no good, and involved in elaborate practical jokes. It comes to Hasmukh's attention that his sons have been lying to him about their college grades — in studies and sports — and have not been attending school for the last three years. As a result, they are kicked out of college and, ultimately, their home. Later, one of their practical jokes gets out of hand, and Bunnu disappears, presumed dead. Munnu gets involved in the conspiracy of killing Bunnu. Meanwhile, from a small Indian village, Bunnu's identical cousin, Gauri Shankar, arrives in town. He is mistaken for Bunnu which leads to hilarious misunderstandings and constant uproar.
