In the 1980 French countryside, farmer Jojo and his ill-tempered wife Lulu hate each other, though their respective interests speak against divorce. The only thing that keeps the oppressed Jojo from murder is the threat of the guillotine...

The film is set in Marais, a quiet region along the banks of Loire river in 1918. Riton is afflicted with a bad-tempered wife and three unruly children. Garris lives alone with his recollections of World War I trenches. Their daily life consists of seasonal work and visits from their two pals: Tane, the local train conductor and Amédée, a dreamer and voracious reader of classics.

After serving together in the French Foreign Legion, a mercenary and a doctor leave the service and go their separate ways. Later, they are reunited and become involved with a caper involving millions in a high-security safe. The two men become locked in during a holiday weekend as they attempt to crack the safe's combination.
