Demonoid

“Up from the depths of hell comes the ultimate horror!”

Jennifer Baines (Samantha Eggar) travels to Mexico to see her husband Mark (Roy Jenson), who is trying to reopen a mine, and finds the workers will not go underground, afraid of an ancient curse. To prove there is nothing down there, the couple walk in themselves. Alfredo Zacarías builds the film on a possessed left hand that takes over whoever it touches, and on the idea that dismissing a warning does not make it go away.
