Nothing occurs onscreen. There is reference to a party where something "illegal in any country" occurred, and to someone "screwing" a woman.

One man is punched in the face and is left unconscious in a situation where he will die. Two other people are killed in an accident, shown from a distance without sound.

Two uses of fuck and 6 uses of shit in the English subtitles.

People have wine with dinner, and one character begins to drink heavily but is told to stop by another.

The whole story involves a group of people trapped in a room that they must escape from or die, so there is moderate tension throughout.
