In post-apocalyptic California, brothers Billy Lee (Scott Wolf) and Jimmy (Mark Dacascos) are highly trained martial artists living in the ravaged city of New Angeles. The pair have been trained by Satori (Julia Nickson), who took them in after their parents died. When Satori finds herself pursued by evil overlord Koga Shuko (Robert Patrick), who's intent on possessing her mystical dragon medallion, the siblings are charged with protecting it from Shuko and his henchmen.
