But when a little boy introduces himself as the powerful wizard Merlin, and tells Lils they're in fact the reincarnation of King Arthur, life for Lils and their group of friends is destined to change forever.

Lils' dreams offer glimpses of King Arthur's life in reverse, gradually convincing them of their true identity.
