Terwijl hij wordt overgebracht naar een psychiatrisch ziekenhuis, slaagt seriemoordenaar Gassot erin te ontsnappen. Hij komt in Marseille terecht en wil van daaruit de oversteek maken. Hij wordt echter verliefd op het jonge hoertje Gerda en neemt haar mee naar Parijs. Le Guen, een commissaris op leeftijd, wordt opgetrommeld om Gassot te vinden. Hij was immers diegene die Gassot de eerste keer kon arresteren.
Nee, helaas is Le tueur nog niet beschikbaar op Netflix in Nederland.
