In this crime story, Antoine (Jacques Bonnafe) is suddenly called home from the North Sea where he works on an oil rig; his wife's body has been found in the Seine. Not accepting the hypothesis that this was an accident or a suicide, Antoine starts to look into his wife's friends and acquaintances and discovers that he never really knew her at all. One of her female friends turns out to have been her lesbian lover, and the two were involved in bilking money from a bank. An accountant at the bank is trying to reclaim a stolen bank code somewhere among the deceased's belongings, and poor Antoine has just begun to scratch the surface of his wife's hidden life.
