Der freigelassene Kindermörder Guy Béranger wird von einem wütenden Mob in die Wälder von Vielsart verschleppt. Polizistin Chloé Muller muss sich ungewöhnliche Verbündete suchen, um Béranger zu befreien, bevor er der Selbstjustiz zum Opfer fällt. Unterdessen verschwindet ein weiteres Kind.
Vincent and his gang are in hot pursuit after Béranger, and succeed in getting their hands on the ex-criminal. Chloé has no other choice than to assemble a team, this time with both of the Stassart brothers (Lucas and Patrick), the only two capable of tracking Vincent across the immensity of Vielsart forest. The unlikely trio is in a race against time: they must find Béranger before Vincent and his gang take justice into their own hands. For Michaël things get complicated when it seems that a new child (Laurent) has gone missing in Vielsart.
Chloé et Lucas demandent l'aide de Patrick pour retrouver Béranger, tandis qu'un nouvel enfant du village est porté disparu.
Vincent og gjengen hans bestemmer seg for å ta loven i egne hender og gir seg ut på jakt etter Guy. Planen deres er å ta ham med til en isolert hytte i skogen. Samtidig forsvinner enda et barn.
