A geeky group of Live Action Role Players (LARP) must summon their inner heroes when one of them inadvertently conjurs-up a sexy succubus with diabolical intentions. Deeply depressed following his messy break-up with Beth (Margarita Levieva) forlorn metal-head Joe (Ryan Kwanten) is abducted by his fantasy-prone roommates (Peter Dinklage, and Steve Zahn) and inducted into the world of LARP - where imaginative gamers assume the roles of knights, wizards, and maidens. As foam swords are drawn and cardboard battle-axes clash, Joe finds himself starting to have a good time when one of his roommates - a would-be sorcerer - casts a spell that actually works. Now, a cruel succubus has crossed into our reality, and she's claiming the lonely LARPers one-by-one. To make matters worse, she's assumed the form of Beth, which makes her nearly irresistible to Joe. With the evil strengthening and the body count rising, Joe and his roommates realize that in order to stop the seductive demon, they must cast aside their fake weapons, and summon the courage to fight a force of pure evil.
