During fashion week, the barely-alive body of a glamorous former model is found hanging in the upper levels of the Eiffel towers iron structure. At first, her lover's estranged wife is suspected he apparently wanted to leave the model to return to the mother of his children, but the model refused to let him go. But then Jo finds another trail that leads to a 22-year-old stripper in Pigalle, dancing in a Josephine Baker revue. The stripper is the dead model's illegitimate daughter she gave up for adoption at birth.
