Two bodies entwined, cast in concrete. This is the strange crime scene our Invisibles find themselves at. All except Duchess, who has joined her family to attend her cousin Laeticia's wedding. While the team discovers that these two young people without identities have nothing to do with each other, Duchess realizes that her uncle is hiding something within the castle where the entire family is gathered. While nothing seems to connect these two stories, Ben and Marijo will soon make a discovery that will change everything. Darius, for his part, tries to help Leïla, who doesn't seem to see the trap set by Chistera, which is closing in on her.
