A well known Parisian inspector becomes involved in an investigation while on holiday.

As every year, chief inspector Paul Bellamy spends a few days with his wife Françoise in the family house in Nîmes. Jacques, Paul's stepbrother, turns up unawares, which is bad news since the fellow is an alcoholic good for nothing. Also annoying is this stranger at bay who asks Bellamy for protection. Farewell peaceful holiday!—Guy Bellinger
