Jared's plane has crashed in the Alberta wilderness, and Kyle is first on the scene. When Jared insists on hiking up the highest hill in search of cell phone reception, Kyle hesitates; his Cree grandmother has always forbidden him to go near it. There's no stopping Jared, though, so Kyle reluctantly follows. After a night spent on the hilltop -- with no cell service -- the teens discover something odd: the plane has disappeared. Nothing in the forest surrounding them seems right. In fact, things seem very wrong. And worst of all, something is hunting them.
