Snow White

The king decides that since his daughter Snow White, whose mother died in childbirth, is old enough to marry an already-chosen prince, it's time now for him to remarry, but his evil bride stops at nothing to eliminate her stepdaughter as a 'beauty rival' and cut every other tie with the late queen. She mounts he throne after the softy king dies at the news that Snow White was devoured by a wild beast. In fact, she ordered the royal huntsman to bring her heart as proof of death, but instead he shot a deer and left the princess in the forest, where she found the messy home of the seven miner dwarfs and became their housekeeper. Informed by her magic mirror that princess lives beyond the mountain, she incarcerates the huntsman and repeatedly passes through in disguise to offer magical death sentences, which are accepted naively, but each time she's saved by the dwarfs, the last time mostly the prince who came looking for his bride, having been incognito at court as the huntsman's inconspicuous assistant.
