"Wildcats" is an episode from the Nightfall radio drama series, written by Otto Lowy and based on a German short story by Christian Noak. The story follows Julian, a traveler who mistakenly gets dropped off at a remote outpost with no way to return home until the next morning. Seeking shelter, he finds himself at the Blue Trout Inn, a decrepit hotel run by two elderly sisters. However, the sisters have a dark secret—they administer morphine to their guests and fight like wildcats.
