One of the segments of this anthology TV movie co-directed by John Carpenter is "The Gas Station," in which a young female gas station employee has a run-in with a killer who escaped from a mental hospital in Haddonfield, Illinois. Haddonfield, Illinois is the setting of Carpenter’s film Halloween. Since the Halloween movies take place in the CU, so do the three stories in Body Bags, which take place in the same universe per the film’s bookends.
