Four friends, Gangu (Jackie Shroff), Abdul (Nana Patekar), Nihal (Kumar Gaurav) and Gary (Jaaved Jaffrey)- which forms the word G.A.N.G, get together to start their business, but their roots are built on friendship and trust. They succeed in their criminal goals, although Gangu is arrested and sentenced to jail for five years. Before going to jail, he asks them to promise to go straight, to which they all agree.
When Gangu is released, he is pleased to find that Abdul is now driving a taxi, his mother is well looked after, and that Nihal and Gary have also started doing business. It is when Gangu meets his sweetheart, Sanam (Juhi Chawla), and proposes marriage, that he learns that all is not well in their world.
