Teen girls perform a secret ritual at a Purity Retreat and, when one of them begins to see a supernatural entity, the terrifying question becomes what is more dangerous: the demon they’ve unleashed, or the pressure of their controlling fathers.

A young Victoria "Vic" McQueen discovers she has the power to unlock portals that help her find lost objects. As she delves further into this hidden universe, she encounters many other "inscape travelers" - some benevolent, and some who have been corrupted by their power. When Vic encounters Charlie Manx, an immortal who stays that way by feeding off of the souls of children, she makes a sworn enemy of Manx.
