The noose is tightening around Sterenn's secret. Main suspect, Jérémy is summoned by the police and Lyes makes him undergo an interrogation. Dismissed from the investigation temporarily, Sterenn nevertheless discovers the link between the killer's victims and Jérémy is finally cleared. Until when?

Sterenn only has a few hours left to honor her pact with the killer if she wants to save her son. As for Lyes, he is convinced that Mélinda is not a victim of the killer and has more and more suspicions about Jérémy. Sterenn then radically changes strategy and confronts the killer.
