The Mascouche squad must figure out a mess involving disparate worlds: a Mexican cartel, a window tinting business, a retired humanitarian worker, and radio broadcasts of a right-wing intellectual.

The Mascouche squad is investigating a shooting that took place at a window tinting business. Albert Scott Ducharme, a reserved radio host, becomes the police’s number one suspect in the murders.

The detectives examine the scene of Hermano, the mariachi's murder, and call in the anti-gang squad. Jovette shows Constance and Jonas the surveillance footage from the event.

Jonas and Antoine question Dany Lafleur about his garage's employees to get the name of their prime suspect.

The Mascouche team searches Pedro Mendoza's place, and Antoine finds bloody clothing in the garbage.

Albert and Françoise agree to describe the same version of events to the detectives. Their interrogations go around in circles.

A search is conducted at Linda Portelance's warehouse. Yvan-Gilles contacts Constance to tell her something that becomes a major breakthrough in the investigation.
