Ang (The Golden Dragon) protects the twelve Zodiac Temples, while his twin sister Ling (The Shadow Dragon) swears to destroy them.

The show starts when the previous golden dragon has passed on to the afterlife and Ang and Ling Leung, fifteen-year-old fraternal twins are next in line for the Golden Dragon power band. Ang has no belief that he will become the Golden Dragon, as Ling is the best fighter at the dragon dojo. Ling is positive that she will become the Golden Dragon. However, when Master Chin calls upon the power of the Golden Dragon to choose who will be the next golden dragon, it chooses Ang. Humiliated and furious, Ling storms out of the temple and is tempted by the ultimate dark and evil power of the shadow dragon. From then on, Ang is forced to fight his own twin sister.—Anonymous
