The Juniper Tree.

This take on the famously dark Brothers Grimm fairy tale tells of a Wicked Stepmother who murders her stepson and serves him up in a stew to his unsuspecting father. The boy’s sister buries her brother’s bones under a nearby Juniper Tree, and the child’s spirit returns as a singing bird who wreaks vengeance on the evil Stepmother before being restored to life in the bosom of his family.
