You wake up from a coma in hospital after a car accident. You're unharmed, but the place seems deserted. There's no one around, no noise... And when you decide to get up and check out what's going on, you discover that the corridors have been ransacked: there's blood everywhere, bodies and... Strange beings. As you approach one of them, it suddenly attacks you, and you do everything in your power to get away. Luckily, a group of boys arrives in time to save you.
