Sexual innuendo. Very brief scene on the beach with a man on top of a woman. It's implied that they were having sex before they were interrupted, but they're clothed so this could easily be missed.

One of the "tribe" fondles a woman's breast (through her clothes).

Lots of violence and some gore.

A man's semi-mutilated body is seen crawling with maggots/worms.

One of the "tribe" rips the heart out of a man's chest (he's still alive) and takes a bite out of it.

A woman is trying to help a man get up to help him escape and you can see a gaping wound in his back where part of his spine has been removed. She suffocates him to put him out of his misery/save him further pain.

Some drinking, I don't recall any smoking.

Lots of frightening/suspenseful scenes.
