An attempted rape happens near the beginning, but the instigator is stopped. There is a strange religious undertone in this scene that makes it more uncomfortable.
A group of teenagers wake up in some kind of lounge, confused. Some of them are wearing skimpy clothing.
The teenagers all get into a hot tub together. They are quite shy at first, but eventually they all strip. Breasts are seen clearly for at least three minutes. There are a few quick glimpses of pubic regions, male and female. Following the hot tub scene, the group of teenagers are given new clothes. You see partial nudity while the young women are trying on t-shirts.
The group kick back and snort some lines of cocaine, and then engage in sexual acts while visibly high. It is all done in the missionary position. Not too graphic, but lots of moaning and thrusting. A much older male taking part says to others that he will teach them how it's done. Plenty of butts are seen throughout this.
