The premise of the movie is that one family goes to visit another that they met as tourists. While the wife of family A (the guests) is taking a shower, someone from family B (the hosts), presumably the husband, enters the bathroom and starts brushing their teeth. Although the shower has frosted glass walls, and no one can see in or out, the fact that someone walks in on wife A, without knocking or acknowledging the transgression, makes her visibly upset. During a sex scene with couple A, the husband from family B stares at them through a window 38:44-39:50. Later, child A is crying in the middle of the night because she is lonely. Husband B picks her up and brings her to the bed he shares with his wife. He sleeps naked in the bed.
