Sergeants Jean-François Bégin, Tommy Nadeau, and Philippe Desrosiers, and Sergeants Mathilde Lapierre and Carolanne Daigneault, members of the elite anti-gang squad dedicated to thwarting organized crime, raided an apartment where 300 kilos of cocaine were allegedly hidden. The squad members found something other than drugs and reported to Lieutenant Christian Thibault, the head of the anti-gang unit.

At another crime scene, Jean-François warns Élias Viau to change his tone with his team. The animosity is palpable. The anti-gang squad realizes it is also in competition with the gendarmerie. Jean-François has another conversation with Goulet.
