Mr. Mehta hires Naresh and assigns him to go to a remote island to investigate and expose some illegal activities there.

The scientist confides in Naresh that he has invented an atomic ring that when inserted in someone's mouth will turn that person invisible, and subsequently passes away.

The news of his escape creates waves in the underworld and the Boss and Mr. Verma join forces to find Naresh, kill him, and keep the ring for themselves.

Mala decided to take revenge for her dad's murder and joins the Central Bureau of Investigation (CBI).

The remaining story focuses on Naresh, Shyam and Mala's struggle against Boss, Verma, Ram Singh and the gang.
