Synopsis: Mohandas finds out that his trusted employee, Rajan, has been embezzling money from him. He confronts him, and Rajan attacks him, flinging him out of the window of the multi-storied building. The police think that the death is accidental. This leaves the coast clear for Rajan to wed Mohandas' only distraught daughter, Sunita, which he does. Shortly after the wedding, Sunita finds out the truth, and runs away from Rajan; meets with an accident, and ends up with a band of performing gypsies. She meets caravan van-driver Mohan, and is attracted to him. Sunita does not know that she has put herself in danger again - this time at the hands of knife-thrower, Nisha, who loves Mohan, and will kill anyone who gets in her way. To make matters worse, Rajan has not given up his search for Sunita.
