Officers Sean Thompson and Billie Blake are a part of the L.A.P.D.'s new program called 'Martial Law'; a police force that uses martial arts to subdue criminals in situations where guns are a no-go. They soon find themselves pitted against career criminal Dalton Rhodes, who is also a master at rare forms of kung fu and the last practitioner of the deadly 'dim-mak' (death touch) technique. When Sean's baby brother Michael is recruited by Rhodes the crusade against the criminal mastermind becomes very personal.
