Dragon Kong, a victor of a millionaire's martial-arts contest, is about to begin the most dangerous mission of his life. For his prize, the millionaire's ravishing daughter Susan, has been stolen - kidnapped by a Ninja sect headed by Tiger So, a legendary Ninjitsu super-foot. Why Tiger has taken Susan, Dragon can only guess, but as the shocking truth begins to dawn, and the final showdown approaches, the violence of the Ninja reaches its fatal peak.

A couple camping in the woods is attacked by a trio of thugs and the wife is beaten and raped. A few months after the assault, she is hunting down the three (who happen to be diamond smugglers) by posing as a dealer looking to sell some stolen merchandise. Meanwhile, her Interpol agent husband is doing some tracking of his own in the hopes of bringing them to justice. As they make their plans, a group of ninjas is watching from afar, waiting to make their move.
