A woman named Helene Delambre (Patricia Owens) phones her brother-in-law, Francois Delambre (Vincent Price) to tell him that she has just murdered her husband. Francois calls in the police and she admits killing him but refuses to say why. Later, Francois tricks her into telling the story to him and Police Inspector Charas (Herbert Marshall).

He has a number of setbacks including his first attempt to teleport something live when he thinks he has ironed out the earlier problems. The family's pet cat vanishes from one booth but does not appear in the other booth, and all that can be heard is the disintegrated cat's meow.

The first time works, but, unknown to him, a fly enters the cabin with him and the two are hopelessly scrambled together.
