Original title: What the Law Will Do

Advocate Gautam Mehra lives in Bombay with his wife, Anju, and a daughter, Rakhsa. One day while returning from court he sees a woman being molested. He stops, phones the police, and then tries to stop the molester, in vain, though as he gets attacked and loses consciousness. But the police do arrive and arrest the molester. Raghuvir's attempts to convince Gautam to change his testimony are in vain. Gautam goes on to testify against Raghuvir Singh, and gets him sentenced to seven years rigorous prison.
