In a post-apocalyptic future Los Angeles that is now known as New Angeles, brothers Jimmy (Mark Dacascos) and Billy Lee (Scott Wolf) hold one half of an ancient and powerful medallion, and they are forced to defend themselves from the danger it poses to everyone. The job of protecting the medallion becomes even more dangerous when evil Koga Shuko (Robert Patrick) discovers that they possess the other half of the Double Dragon Medallion. Shuko will stop at nothing, including sending his henchmen lead by Bo Abobo (Nils Allen Stewart) after them, to bring the medallion's two pieces together to use its powers for his evil designs. Along the way the brothers receive help from the PowerCorps and its leader Marian Delario (Alyssa Milano).
