As the result of the curse of a once-beautiful witch (Meryl Streep), a baker (James Corden) and his wife (Emily Blunt) are childless. Three days before the rise of a blue moon, they venture into the forest to find the ingredients that will reverse the spell and restore the witch's beauty: a milk-white cow, hair as yellow as corn, a blood-red cape, and a slipper of gold. During their journey, they meet Cinderella, Little Red Riding Hood, Rapunzel and Jack, each one on a quest to fulfill a wish.
