The first scene depicts a few naked men from the back as they are bathing. Naked women are also visible, but only very brief glimpses of their buttocks at a distance.
A sex scene takes place about half way through the film. While it has no nudity and is seen from outside a window, its sexual content is quite clear, and the camera returns to the scene three times. We see a man disrobing a woman, we see her bare back, him grabbing her behind, some very obvious thrusting and moaning sounds.
