Three Couples

Three married couples gather at a country house to celebrate the forty-eighth birthday of one of them. For everyone, it's a reason to take a break from children, endless bills, and elderly parents. After an evening at the bar, the birthday person suggests a game — to switch partners for one night. It seems that no one took this idea seriously, but at some point, several people go missing from the library. The next morning, no one talks about what happened. But the birthday person's wife is no longer speaking to him, his girlfriend is looking at him strangely, and it seems that everyone knows a little more than he does. What happened that night? And what will the evening, which someone does not remember and someone cannot forget, mean for each of them now?
