When attending a party at the chateau they are staying in for a seminar, the team finds themselves in the midst of a hostage situation: Claire Chassaigne, armed with a gun, seeks revenge against Cyril Corbin, the owner, apparently for a long-standing trauma. Adèle manages the situation in the best possible way to avoid having casualties and makes Claire tell her story, while she waits for Rocher to release them.
