Always quick with a quip, even private eye Nick Trayne (James Dunn) is temporarily speechless after he discovers a missing millionaire inside his own home...minus half his brain! It's up to Trayne and his lovely assistant to get to the bottom of the puzzling and macabre case, as the victim's near-catatonic state prevents him from supplying any helpful clues. Joan Woodbury, Gus Glassmire also star in this spooky, suspenseful mystery. AKA: "A Walking Nightmare." 61 min. Standard; Soundtrack: English.
