The Xiaolin Warriors uncover a mysterious Shen-Gong-Wu that holds a secret power: Once unleashed, it takes the form of a dragon and turns anybody it comes across into a sapphire statue. It all rests on Dojo to stop the Sapphire Dragon ... for everyone else has been turned to sapphire.

After helping the Warriors acquire a new Shen-Gong-Wu, a Russian vendor named Vlad joins the Xiaolin Dragons-in-training. When Omi uses the new Shen-Gong-Wu, Crystal Glasses, he sees that he becomes evil in the future. Upon seeing this, he quickly leaves the Xiaolin Temple, deciding that he can no longer continue to be a Xiaolin Dragon-in-training.

The Warriors travel to Texas once again looking a new Shen-Gong-Wu but run into some trouble as soon as they get there. The Black Vipers, an all-girl motorcycle gang, capture the Warriors and keep them prisoner in a cave. Clay learns that one of the bikers is his sister, and that she's been holding a grudge against him their whole life. Can the Warriors escape unharmed?
