A weekend camping trip turns into a frantic fight against the supernatural when an ancient demon and a fearsome female warrior bring their eternal battle into the present day. Jason Parks is trying to win back his ex-fiancee, Jasmine, by arranging a camping trip with the lost love in question, his best friend, Ricky, and their witchcraft-obsessed friend, Renee. Little does Jack realize that Jasmine has switched teams--these days she's more interested in seducing Renee than marrying the man she once loved. But lately Renee's been having horrible dreams about Summer Vale, a little girl who vanished without a trace 20 years ago. When Renee attempts to contact Summer's spirit, she inadvertently opens an interdimensional portal and unleashes a vicious demon. Fortunately for the frightened campers, a grown-up, sword-wielding Summer manages to get through the portal as well, and sets out to slay the malevolent hell-spawn.

Two years after Jason Parks (Landy Cannon) saved Warrior Princess Summer Vale (Brigitte Kingsley) from her life hunting Killopoths in the demon dimension, a sudden surge of supernatural activity and violent attacks have resurfaced on our plane beyond the normal parameters of the portal. The Rising Dark Agency, a black ops division of the government headed by Colonel Haggerd (Michael Ironside), suspects that the mystic strikes suggests the work of Mardock, an evil Demon-god capable of destroying worlds. When a new demon sub-species disrupts Summer's wedding and eats her fiancée, the war on the new Demon Lord begins. With her group of misfits and their BFG's - Summer sets out to destroy Mardock, but no one is prepared for who they find behind the Dark Lord's ascension.
