A few seconds of full rear nudity of a man who strips down to jump into the sea.

Women in non-revealing underwear very briefly a couple of times, and in bikinis lying on the beach.

A couple of occurrences where a person's unslept-in bed implies that a man and a woman slept together.

Hardly any.

Fairly frequent cigarette smoking, and social alcohol consumption. Two characters get drunk and stumble home one evening.
