A girl tells a boy to drop his pants so they can engage in oral sex(nothing is shown.)
One conversation between a young couple mentions how the guy is never going to get sex again from her after he scares her for fun.
A couple who are rock climbing meet the cannibals abruptly and the man is first killed and thrown off the cliff (we see blood on his head and face), followed by her having the rope cut and falling. She is then dragged away by an unseen attacker before she can reach her car.
A woman finds a freshly severed ear on the ground.
A girl is grabbed around the mouth with barbed wire that tears into her flesh and sprays blood on the vest. She writhes and screams as she is lifted off the floor by her attacker. We see her later, dead, still with barbed wire around her mouth and blood pouring from her wounds.
The cabin in which the three inbred mountain men live has human remains in jars; teeth, livers and other body parts.
A dead woman is skinned and carved for cooking. Most of this occurs off screen (but you can hear it vividly.) Blood pours down her arm and pools on the floor. Her semi-naked and mutilated body, missing a leg and hands, is later shown.
The characters stumble upon a clearing full of wrecked cars, many of which are covered in blood where other people have been killed.
A man is shot in the leg, which bleeds profusely.
A bloody dead body falls out of a car.
A man is shot in the back with multiple arrows, the last one going all the way through his body to emerge through his chest.
A woman is hit in the mouth with an axe; it severs her head leaving the lower part of her body to fall away and we hear a squish as the axe is removed from the remaining part of her head.
A man is shot through the eye with an arrow and falls to the ground dead. The body is taken to the cabin, put on a table and his killer hacks at his neck with a hatchet, eventually decapitating him.
A man is hit by a speeding car.
One man is shown engulfed in flames and is then stabbed in the chest with a car jack.
A man is hit with a hatchet in the chest while being held with a chain around his neck, and another is shot with an arrow in the back of his head.
Charred remains are shown after a car explosion.
Overall, it's a film about a cannibalistic family who are ultra violent, and survive on people who cross their path. It's pretty heavy on the violence and gore.
There are constant obscenities used throughout the film including 9 uses of fuck. Profanity is used in this, but typically in fear or under one's breath. Being quiet is a huge part of how they are surviving which is why it's light on profanity compared to many similar/comparable films that are as violent as this.
A young couple smoke marijuana. While searching his totaled car, they realize that he's a doctor or studying to be one, and wonder if he'll write them illegal scripts. Tobacco use.
The appearance of the three mountain men is frightening, as they have many deformities and distortions of their faces and appendages.
The acts they commit are highly disturbing, as they are insane cannibals who kidnap, kill, and mutilate people.
There are several jumpy scenes, including chasing, hiding, and some scenes set at night, such as mountain men suddenly jumping down into a tree, and a man suddenly swinging an axe at one character out of nowhere.
