Updated for the Internet era, Du Welz’s remake of the classic The Honeymoon Killers is based on the true story of ’60s serial killers Martha Beck and Raymond Fernandez, who met women through personal ads, moved in, and then murdered them. Here, lonely Gloria meets conman Michel through an online dating service and quickly falls for his charms. When she discovers he’s swindled both her heart and her wallet, she agrees to help him seduce other women just so she can be with him. Gloria’s obsession with Michel turns their relatively innocent hustle into something much darker when she jealously murders his subsequent love interests.
