The murder of Edgar Girault plunges the Riviera even further into chaos. Giulia, suspected by Raven, is narrowly saved by Joseph Neuville, the charming son of the newly arrived hotel owner. But Raoul Delaunay continues to blackmail her to obtain a compromising notebook. Meanwhile, Marthe Pontavice-Caron testifies against her working-class son-in-law. She believes Jean Berthier had a motive: he had just learned that Louis was not his biological son. Blanche is released. But tensions rise at the town dance, where Eugénie sees her husband taken away by the police. For Léonie, the evening turns into a nightmare.

Léonie, Eugénie, Blanche, and Giulia will join forces to bring down the man they know is responsible for Félix's murder, and perhaps the others'... Delaunay. Will they succeed? And isn't the truth about the murders of Jacquart and Edgar Girault somewhere else? In any case, the summer of '36 was a scorcher.
