One night, after becoming infatuated with Nikki's girlfriend Olala, the Prince dispatches his troops to abduct her. Nikki follows them to the palace where he assaults the prince, assumes his identity and banishes him from the castle. Nikki then initiates a new, just administration while the real Prince finds contentment in Nikki's humble life. Upon his impending marriage to Olala, Nikki sends for the Prince and they revert to their true identities.
