Sergeants Jean-François Bégin, Mathilde Lapierre, Carolanne Daigneault, Tommy Nadeau and Philippe Desrosiers, all members of the elite Anti-Gang squad tasked with thwarting organized crime, raided an apartment where 300 kilos of cocaine were allegedly hidden. There, they find something other than drugs and report back to Lieutenant Christian Thibault, the squad’s commander.

Mathilde discovers a secret of Carolanne’s, who begs her to keep it to herself; the team learns more about the murdered dealer’s ties with the man he worked for, Gabriel “Gégé” Goulet.

On another crime scene, Jean-François warns Élias Viau to change his tone with his team; the animosity is palpable; the Antigang squad realizes that it is also in competition with the RCMP.

Mathilde and Carolanne realize it isn’t easy to get the relatives of a biker to talk; Cédric Murphy, the son of Irish mob boss Dan Murphy, tells his brother Noah to be more careful in choosing his girlfriends.

Jean-François and Carolanne go to a street in Parc-Extension that was the scene of a shooting. A young member of the Jewels street gang lost his life there. Christian calls a meeting to take stock. Fanny has breakfast with Karine in a diner.

The latest shooting causes quite a stir, and Chief Inspector Charbonneau, who comes to put pressure on the team, is rebuffed by Christian and Jean-François. The latest shooting unsettles more than just law enforcement. Denys Marchand meets with the godfather of the Irish clan, Dan Murphy, and Joseph Petit-Frère, a respected Haitian kingpin, to assess the situation.

Fanny does Rebecca’s hair, an escort who works at the Quickie strip club, and takes the opportunity to coax a few confidences out of her about her business. Carolanne’s pregnancy is becoming a less and less well-kept secret.

Jean-François works tirelessly to push forward the investigation into the proliferation of Colt .45s in Montreal, a type of weapon linked to four recent murders. He invites Christian to dinner: he has serious and surprising information to share with him.

Christian is visited by the Minister of Public Security, Antonin Lavergne, and his chief of staff, Josiane Laramée. Having come from Quebec City, the duo wants to get a clear picture of the violent clashes proliferating in Montreal. Jean-François has scheduled a meeting with Inspector Zhao of the SPGM to ask him for a favor. The team is making progress in the case of the Colt .45s.

Fanny calls Karine to invite her to dinner. Myriam Dion, from Internal Affairs, wants to meet with some members of the team to clarify certain matters. Jean-François has a new confrontation with Bruno Monette, from the RCMP. His daughter’s relationship with Noah Murphy comes back to haunt Tommy.

Relations between Tommy and Léonie remain tense. Jean-François asks Carolanne and Mathilde to summon Marilou Caron again for an interview. Bénédicte meets Karine and Fanny at the hair salon.

Fanny visits her broker to invest some money; he recommends that she buy bonds. Christian asks Philippe to go see the kingpin Joseph Petit-Frère in order to persuade him to ease the tension between the street gangs.

Philippe shares certain information with Joseph Petit-Frère to make him understand the seriousness of the situation. Denys Marchand and Gabriel Goulet are also worried about an escalation of the street gang war. Jean-François and Mathilde go to see Denys Marchand to tell him that they have received credible information that a price has been put on his head.

Christian gathered the whole team to review their investigations. For his part, Denys Marchand summoned Dan Murphy and Joseph Petit-Frère in a parking lot away from prying eyes. Carolanne is starting to lose patience with those who make remarks about her pregnancy. Jean-François and Christian argue about a strategy. At home, Carolanne and her husband David realize that their two children, aged 10 and 12, do not look kindly on the arrival of a newborn.

Denys Marchand takes stock of his potential enemies with Gabriel Goulet. Jean-François is convinced that Bruno Monette, from the RCMP, stole 50 kilos of the drugs seized by the police. He’s not the only one who thinks so. Christian, however, asks him to “keep it quiet.” A multiplex in Saint-Laurent is on the investigation team’s radar.

Karine expresses her exasperation to Gabriel because he is slow to change his life. Denys Marchand has a tense discussion with Cédric Murphy and his father, Dan. Bénédicte meets up with Karine and Fanny at the salon. The team devises a strategy to rent an apartment near the one they are interested in within the Saint-Laurent multiplex.

Zoé talks with Léonie to try to find out what her feelings are for Noah Murphy. Tommy shares his concerns about this with Jean-François. The efforts invested in the multiplex are starting to pay off. Christian continues to wonder which side to take in the case of Bruno Monette.

Joseph Petit-Frère issues another warning to Wesley and Jimmy. Christian has a tense meeting with high-ranking officials from the Sûreté and the RCMP.

Eve Gladu confirms that money is indeed passing through the multiplex. She immediately alerts Christian. The squad grows concerned as two key figures from the criminal milieu are nowhere to be found. David reproaches Carolanne for caring more about her work than her pregnancy. Christian tells her she won’t be able to keep working indefinitely in her condition.

Jean-François and Bénédicte wonder if it’s a good idea to continue their affair. Mathilde and Carolanne question Marilou Caron at length. The atmosphere is tense between Fanny and Denys.

Pressure is mounting on Wesley Normand. During the meeting, Jonathan explains that it’s impossible to bypass the multiplex’s alarm system. Mathilde suggests another solution. Christian reproaches Jean-François for overstepping a bit.

Three people lost their lives after swallowing pills circulating on the street. The homicide squad asks the anti-gang unit to take over this high-profile case. Philippe argues with his mother, who reproaches him for doing nothing to help his half-brothers, who have gone down the wrong path.

Tommy feels embarrassed when Mathilde and Carolanne encourage his daughter, Léonie, to do so.
