Chantal Pouliot, of the Quebec police force, is relegated to mind-numbing desk duty because of a case that went wrong six months earlier. A break comes her way in the form of a white-collar cyber-crime case, something she hopes will help restore her status as an undercover detective. The downside is having to collaborate with an RCMP team that will join her in Quebec City.

When the safe, tedious job she envisaged turns to murder with a potential link to organized crime, Chantal is thrown back into the life she wanted, with Jeff Lafond by her side once again. But somebody is playing games with them, and that person is aware of her past. Is someone close to the investigation involved? What is the purpose of the game and how many people will the murderer sacrifice in the race to win it?
