When Jason Parks (Landy Cannon) invites his friends and ex-girlfriend on a camping trip with the hopes of reuniting with her, it becomes the outing from hell, as an otherworld portal opens for a long-missing girl, who's now a battle-ax-wielding woman. Not only will Jason discover that his ex, Jasmine (Vanessa James), and friend Marlene (Haley Shannon) are a twosome, but also that the bikini-clad warrior woman has demons on her trail.
