Alex and Camryn get two successive surprises on their 21st birthdays: they're twins separated at birth, and they're actually royal witches who were sent to the non-magical world to protect them from a malevolent force that invaded their kingdom and killed their father. Now reunited, they must learn to harness their magic to drive back the darkness once and for all. It's all the sisterly bonding of "Hocus Pocus," but with witches trying to save the world instead of harm it!
