For Maud, the return from Italy is a little brutal: taking advantage of her absence, Joseph seems to have returned to his faults. Mathias, for his part, will quickly take advantage of a tense mother-son relationship to put Joseph out of harm's way. But the latter, who is starting to see clearly in Mathias' game, does not intend to let it happen.

While Maud sees her daily life crumbling, Mathias shifts into higher gear. He will do everything to isolate Maud and keep her by his side. But an event that he did not expect will come to thwart his plans... For his part, Joseph gets his hands on a witness from the past who could well change everything.
