Generation after generation, immortal Guardians like Santa Claus (Peter Ramsey), the Easter Bunny (Nancy Bernstein) and the Tooth Fairy (Christina Steinberg) protect the world's children from darkness and despair. However, an evil boogeyman named Pitch Black (David Lindsay-Abaire) schemes to overthrow the Guardians by obliterating children's belief in them. It falls to a winter sprite named Jack Frost (Nimit Manatpon) to thwart Pitch's plans and save the Guardians from destruction.
