Two women are in a boat, one of them is reading topless, breasts visible.

A man and a woman are having sex on a raft and she tells him to go scuba diving with her after they are done having sex. (Slight view of her breasts and nipples are seen).

In the beginning after first sex scene, woman strips nude and brandishes a knife and cuts her lovers speedo and they have sex. (Full frontal female nudity) are very clearly seen up close on the camera.

A young boy and a girl are seen on kissing on an island and later go off on a small boat together. They fall asleep in each others arms (Presumably they had sex, but no sex scene or nudity is ever shown).

Gory piranha attacks including flying piranha that bite several people on the neck.

Some profanities including at least one use of 'fuck'.

Some social drinking.

The piranha attacks are intense.
