“Wolf in the Fold” (season 2, episode 14) - TOS slasher
Years before Freddy Krueger and Jason Voorhees, Star Trek unleashed its own proto-slasher in “Wolf in the Fold.” This terrifying episode begins with a horrible murder and then becomes a mystery with supernatural threats. The person who committed it isn't a man at all. Rather, Redjac is an immortal entity, who was known as Jack the Ripper on Earth and countless other names elsewhere.
The Enterprise is a location of mental torment because of this terrible blend of history and horror. Members of the crew are possessed, women are targeted, and fear is prevalent. Parts of the story may seem old-fashioned to current viewers, but its impact can't be overstated. This episode foreshadowed the "unstoppable killer" cliche that would later dominate horror cinema.
"Wolf in the Fold" is a mix of horror based on historical events and on the supernatural, all told through speculative science fiction. It dares to ask the question, "What happens to evil when it reaches the stars?"
