Generation after generation, immortal Guardians like Santa Claus, the Easter Bunny and the Tooth Fairy protect the world's children from darkness and despair. However, an evil boogeyman named Pitch Black schemes to overthrow the Guardians by obliterating children's belief in them. It falls to a winter sprite named Jack Frost and a water sprite named (y/n) Storm to thwart Pitch's plans and save the Guardians from destruction.
