Blood Frenzy (1987)

Sex is implied but not shown. There is hugging and kissing. One woman wears a see-through bra showing her nipples.

A drunken man falls out in a trailer, his pants down and his buttocks showing briefly.

One of the women, a lesbian, urges another woman to have sex (offscreen). Later the woman says she enjoyed it and had never done that before.

One woman lies down to sun herself wearing only a bikini. She is shown from different angles for several seconds. A man approaches and looks at her. She gets up and tries to seduce him but he rejects her and walks away.

Two cases of implied heterosexual sex.

At least 3 throats are slit with blood coming out. One woman's stomach is carved multiple times. There are a couple of stabbings with bloody knives.

One man is frequently drunk and seen drinking beer.

There is an overall feeling of dread throughout as characters are killed off. This continues and increases near the climax of the film.
