Padudu, a 12‑year‑old apprentice witch, is chosen to represent her town in the coliseum. Donning a magical fish costume that keeps her warm and fed, she sets off on her journey. Along the way, she is swept by a river into Dance Valley. Mayor Koffy captures her and locks her in a dungeon, hoping to eliminate her as a competitor for Dance Valley’s own coliseum. Inside the dungeon she encounters the mysterious witch Nonononn, and the two join forces in a magical struggle for survival.
