Josephine has been blackmailed by the traffickers into defending their smuggler, Maria. Ali and Laure follow whatever leads they can tease out of the new line of enquiry, but how much information can they get out of their new arrest?

Captain Beckriche and Judge Lucie Bordieu must find common ground - and they do.
