Plot

One summer mid-afternoon, Antoine (Darroussin) leaves his insurance firm job to meet up with his wife Hélène (Bouquet), as they are to fetch their kids (somewhere distant, but it is not explained exactly where they are or who they're with), and then head on to his in-laws' place in the Basque Country for two weeks' vacation. He wants to beat the traffic (and the two million cars that will be on the road). They arrange to meet at a local bar, but she arrives late, annoying him. When she arrives, it's clear their relations have been strained for some time.
