Note: the story revolves around prehistoric humans who do not possess modern language or culture, making boundaries and sexual consent muddled and uncertain. A male neanderthal sneakily follows a small group of females, then begins having sex with one as she is bent over to drink water. The female seems surprised, but does not appear to be in distress. The other females do not react. A man tries to initiate sex with a woman, who pushes him away. A different male then grabs her and has sex with her as she seems to scream and protest. The scene is not long, but is graphic. The woman does not appear traumatized afterward, but it does not seem like she wanted the contact either. The same man and woman begin having sex again, this time seemingly consensually. The woman protests at first, but only because she wants to change positions. A man is captured by another tribe, who then make him have sex with several of the tribe's women. The man does not seem distressed or bothered by this, and the women are clearly interested.
