When an old friend (Milo Ventimiglia) turns up dead, mourning teenage gamers (led by Jon Foster) uncover an ultrarealistic video game based on the true story of a 17th century hellcat known as the "Blood Countess" and find it impossible to resist the temptation to play. Each eventually shares the fate of his or her gaming persona and dies violently. But if there's no one left to play, who will defeat the countess? Frankie Muniz co-stars.- Netflix
