During the Heylin Eclipse, all light vanishes from the world. It lasts for just a few moments, but a few moments in sheer darkness is all it takes for a horrid monster called the Jiuwei Hu, to awaken and wreck havoc upon the world. If left alone, the Jiuwei Hu can be expected to kill millions and eradicate goodness forever. Unfortunately for the six Xiaolin monks, the Jiuwei Hu can only be stopped by finding legendary talismans containing the power of the Four Symbols, which can only be controlled by the chosen ones of the Symbols. To save the world, the Xiaolin warriors must not only find these talismans, but harness their power and use them to defeat a threat unlike anything seen before.
