In the beginning of the film, right after they get stranded, Peppe makes the woman be his slave by being verbally, mentally, and physically abusive. Although this is done by Pepe in a tongue in cheek manner to prove a point, this is more of a role reversal situation than reality. He is teaching her a lesson about how she treats others. This lesson in no way excuses his actions.
On one extended scene, the woman and man fight. She hits him and kicks him and he trips and grabs her. Towards the end of the scene, he catches her, pulls off her pants, and is on top of her as if he is going to force himself on her.
