Orphaned as a child, Arun Verma (Anil Kapoor) has dedicated his adult life to looking after orphaned children, in a house where he is unable to afford to pay the rent nor even day to day expenses for necessities. He decides to rent one of the rooms, and the tenant is a newspaper reporter named Seema Sohni (Sridevi), who happens to dislike children. Internation crime lord and terrorist Mogambo (Amrish Puri) takes an interest in his very house to store his firearms, and other weapons, and sends his men to force Arun to vacate. Arun and some of the children are beaten-up and threatened with dire consequences if they do not vacate the house. Arun's dad's friend Professor Sinha (Ashok Kumar) shows Arun a device that will make in him invisible, and thereby he will find a way to fight to keep the house.Wikipedia
