Prince Percy arrives in San Francisco for an arranged wedding, but before the wedding, he goes out for a pub crawl and gets robbed on his way home. Zoe, who lives with her mother, Gwen, is supposed to dissect a frog at school but decides instead to release the frog in a park. Before letting it go, she kisses the frog, and just as it hops away, Percy wakes up in the bushes. He has lost his memory, and Zoe believes he is a prince. She takes care of him, and soon she has a plan for how Percy, with his British dialect, will introduce himself and become her new nanny, hoping that he and Gwen will find each other.
The movie doesn’t lack charm entirely, but it doesn’t quite hit the mark. The overly obvious caricatures can sometimes become a bit tiresome.
