Wenn den Produzenten nichts mehr einfällt zum Fortsetzen... dann machen sie eben ein Prequel.
At an isolated hospital deep in the West Virginia wilderness, three hideously deformed mutants go on a merciless killing spree. Now, decades later, this family of blood-thirsty cannibals is stalking new prey: a group of young skiers trapped by a blizzard. The abandoned medical wards soon become killing fields as the panicked victims come face to face with a chilling choice -- fight back or die. With bonus footage too graphic for theaters, WRONG TURN 4 takes you to the most terrifying place of all... the beginning.
Da der Trailer u.a. Material enthält, welches in Deutschland trotz FSK 18 geschnitten war, ist der in der 18er-Ecke zu finden.
