Gilou is offered a way out of jail if he agrees to become a police informer, but on the condition that he keeps away from Laure. Meanwhile, the police team focus their investigation on the Paris neighbourhood of Barbès, where vulnerable delinquent minors are being exploited by receivers of stolen goods.

The police investigation screeches to a sudden halt when Souleymane disappears. How and where will they find him? Meanwhile, Laure flouts the ban on seeing Gilou, who has got himself hired as a bouncer in Cisco's nightclub. There he meets the security manager, Cisco's son Titi.

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? And is there sufficient evidence to prove a link between the international smuggling operation and the murder case they are investigating? Captain Beckriche and Judge Lucie Bordieu must find common ground - and they do.

Laure and Ali identify 'The Alsatian' and get to work on a tracking device that was hidden under his car by members of a rival gang. Josephine tries to help Souleymane but her attempts are short of adequate.
