The evil criminal leader Kendrick has kidnapped an elderly biochemist who holds the secret to creating a biological superweapon. The only person who can possibly stop Kendrick and his gang is L. A. cop Sam Kettle and martial arts master Jun Kim (uncle of a little girl also kidnapped by Kendrick). Together, they go to war against an army of ninjas to rescue the hostages and bring their kidnappers to justice.

Warring teenage street gangs provide the fodder for this martial arts actioner. Things really heat up when each gang finds a martial arts experts to train them out to fight.
