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.
