While the team discovers that these two young people without identity have nothing to do with each other, Duchess realizes that her uncle is hiding something in the castle where the whole family is gathered. . If nothing seems to link these two stories, Ben and Marijo will soon make a discovery that will change everything. Darius, for his part, tries to come to the aid of Leïla, who does not seem to see the trap, set by Chistera, which is closing in on her. (thetvdb.com)
