Wolf episode 5 opens with a rather sadistic murder, where the man wearing the hazmat suit and mask strikes again after tricking a young woman into letting him inside her home by posing as an exterminator.
He stabs her to death with a knife after taunting her, before the episode moves back to the present day. As we creep closer to the final episode, we start to learn some dark truths about what's really going on here.
