Exchange student Mai Le arrives in Crystal Cove, and joins the gang at the Blake mansion for a dinner party with Mr. Wang, a visitor from China. There, a Red Wizard attacks and warns them to stay away from the Dragon’s Heart. Later, Mai Le and the gang are attacked by a White Wizard who is after Mai Le’s ring. The Red Wizard saves them, but the ring is already gone. Mr. Chen of the local internet cafe and tea house reveals himself to be the Red Wizard, tasked with protecting the Dragon’s Heart. Because the White Wizard now possesses all four rings, he can steal the Heart. The gang traps the White Wizard, revealed to be Mr. Wang, but the Heart remains missing. Mai Le is revealed to have stolen it, and she is stopped in the harbor by Shaggy and the gang.
