Marc Delvaux, a famous retired police commissioner, lives alone in a large building in the Lyon countryside on the banks of the Saône. When a lawyer friend asks him to house Emma for a while, a young woman who has to testify, he accepts without suspecting that he has just signed his return to the field.
