She's adopted, but her new father can't warm to her, and her mother can't succeed in turning the plain, unresponsive child into the little princess she longs for. When her adoptive mother dies, her greedy aunt takes her in, but hers is not a happy home, and soon Rebecca's life is worse than ever. She longs to escape to the circus that visits her town, with its carefree life and freedom from her past - but will she ever find happiness?
