The film is set in the tropics and many women run around in bikinis throughout. A woman walks into a bedroom with her top off and breasts are barely visible. She attempts to seduce a man but he refuses her. A woman strips down to her skimpy bra and panties & showers. A man pulls out a giant dildo as a joke. He then proceeds to intimately rub lotion on his girlfriend. They kiss and he pulls her bikini bottoms off. She pulls his head down and its implied he performs oral sex on her. She moans and orgasms. No nudity. Two men discuss in vague terms how a woman is a nympho and what she can do with cucumbers.

A man is seen kissing the feet of his gf

A character cuts his own hand and puts it on a background character's face.

R - for strong bloody violence and gore, crude sexual content, brief drug material, and language throughout

Not nearly as graphic or disgusting as Spring Fever, about on par with the first film in terms of gore. However, this movie is much more serious and less comical then it's predecessors

A man cuts another mans throat, his own hand is cut open and blood sprays. Remnants of dead fish line the ocean floor, not particularly gory. Many people die from a flesh eating disease. Most spew blood and some rip off their own flesh. A man goes down on a girl and comes up with blood and gore all over his face, she pukes blood and bile on him. A man tries to pull up a woman, the skin on her arms peels off and some blood splatters. Explorers discover a compartment flooded with blood and piled with human body parts. One body rises up, just barely alive, and is chopped with a hatchet in the skull. Two women in the advanced stages of flesh decay fight each other. They rip off each others body parts and a great of blood & gore is shown.

An example of "plenty" would be Astin's character saying "fucking" during a discussion with a lady scientist.

50 F-words.

Plenty.

A man shows a plastic bag containing marijuana. It is implied that he smoked it with his friend but it is off screen.

Film has a dark and disturbing tone throughout. A man is held hostage and forced to help scientists. A man is left to die in a jail from a horrible disease, he cries and begs for help. Rooms full of bodies. Lots of screaming.
