In 1974, in the quiet suburb of Sainte-Foy, two discontented couples bring their kids to summer camp. Once home, they must face the pitiful state their marriages are in. Unable to deal with their problems, they become the most infamous criminals in the history of organized crime in Quebec City.

Summer 1975. The Delisle and Paquette families once again drive their kids to summer camp. They have three weeks to regain control of their criminal empire. As they try to defend their Organization all the way to Montreal, they realize something: bombs and guns can kill, but nothing is more dangerous than a broken heart.

Huguette Delisle couldn't have fallen any lower, but her vengeance will be all the more terrible in this final season of twists and turns. We return to the Delisles and Paquettes in the summer of 1976.
