L'aprenent de maga comença a sospitar i s'adona que la Val porta un braçalet màgic, que segons els guardians, és un objecte de la llista d'Objectes Màgics Prohibits. Si la Sadie no pot recuperar el braçalet de la Val, la mala sort que ara només afecta la Sadie s'escamparà pel món.

Finalment, aconsegueixen tornar el faraó a la capsa i salvar el present.
