In this martial arts actioner, a kickboxer's life goes into the gutter after he accidentally kills an opponent during an important bout. Devastated, the distraught fighter becomes a street bum until his brother's murder by a drug-lord rouses him into a frenzy for revenge. Kickboxer Johnny Rider's (Dale "Apollo" Cook) target is narcotic kingpin Rod Sparks (Nick Hill). In order to bring him down, Johnny joins Sparks' organization as a goon. His plans to get near Sparks and destroy him, however, are nearly destroyed when dogged detective Bill Williams (Ron Hall), himself a kickboxer and the brother of the man Johnny accidentally killed, enters the scenario.
