Kama Kazi is an international smuggling gang. When the Interpol is about to raid the gang, they move all its wealth in form of gold and silver diamonds by ship, but the ship sinks in a cyclone. An Indian company is subcontracted to salvage the sunken ship and the Indian Intelligence sends its ace agent Himadri Choudhari, and his sidekick Mantu Ghosh along with a Japanese karate master Kitahara.
