The Brigade

While Saïd's group is busy recruiting, they are urgently called back to Versailles: two narcotics officers have been targeted. Ferracci, convinced that the narcotics squad is not sharing its information, puts pressure on the team to find the dealers who shot the police officers.

The BRI is trying to identify the drug dealer who was robbed. Socrates approaches Inès, the superior of the two police officers who were shot. She finally gives him the name of the dealer: La Mangouste. Vanessa, Badri, Julien, and Jill travel to Spain to try to find him.

The gang of drug dealer robbers who kidnapped Mangouste contacts his wife Sadia and demands a ransom. The BRI activates its kidnapping protocol, but Sadia doesn't tell them everything.

Informed by Inès, the BRI tails a drug convoy led by Nina Perez. The truck is attacked by robbers who start shooting. Faced with a highly trained team, the BRI finds itself in serious trouble.

After a violent shootout, the team is in shock. Meanwhile, Saïd is unreachable. Vanessa takes charge of the group. Under pressure, Inès confides in Socrate: Vingre suspects her of double-crossing him.

Helpless, the group follows a lead that Saïd had discovered before his disappearance. But the robbers are still one step ahead, and set a trap for the BRI. Vingre discovers that Inès has given information to the BRI.

Saïd is back. Battered but bruised, he resumes the investigation. The group is getting closer and closer to the robbers: the BRI discovers that a huge shipment of drugs is due to arrive in Le Havre. They know that the robbers will also be there.

Working with the BIS PP group, Saïd's group prepares to intervene as the robbers board the cargo ship. Socrate and Ferracci, meanwhile, are hot on the trail of Vingre.

Saïd takes over as chief of the BRI Versailles, an elite unit specialising in organised crime. Leading officers Badri, Julien, Vanessa and Socrate, he will not only have to prove his mettle but also excel at succeeding the former chief, Patrick.

After Sélim's murder, the team deal with the criminal gang to find the shooters; during Patrick's wife's funeral, Saïd uncovers the true nature of the bond that unites him and Éric Perez.

The team find the identity of the second shooter; Éric Perez reveals to Saïd that he knows the people who got Sélim murdered; Saïd and Julien are following a suspect when they come across Socrate about to intercept traffickers.

Socrate admits to Julien and Saïd that he was recruited to investigate several high-ranking narcotics officers suspected of covering up cocaine traffickers; Jordan, Éric Perez's eldest son, escapes an assassination attempt.

After the operation fails, Saïd is demoted, and Patrick takes over as chief of the squad again; Éric Perez is convinced that the El Hassani gang is responsible for the attack on his son and prepares for retaliation.

The team celebrate the success of the last operation; Saïd confides to his team that he made a deal with the El Hassani gang so that they could help him in his investigation; as Saïd takes over BRI again, the Perez clan lose one of its members.

Nina, Éric Perez's daughter, accuses one of the El Hassani brothers of the murder of one of her relatives; convinced of his innocence, Saïd warns him so that he can flee, and in exchange, he provides information, helping Socrate in his investigation.

Returning from the operation in Morocco, Patrick realises that he was manipulated by the Perez clan to put the El Hassani gang out of the game; Julien finds the trace of the informant who had double-crossed him, and the team prepares to question him.
