Heading on a vacation from exhibiting a gorilla in traveling shows, Bernard Sell and his assistants, Billy Gilbert, Shemp Howard, and Art Miles -- the last is the one in the gorilla suit -- stop for the evening in a haunted house at the invitation of the owner, Jayne Hazard. Minerva Urecal is the housekeeper, Tim Ryan the detective who comes around, and Maxie Rosenbloom shows up as Miss Hazard's chauffeur.
Gilbert and Howard have the mugging turned up to eleven here as they run through many of the gags for haunted-house comedies that have turned up in movies for more than a hundred years. As you might expect from such old pros, their timing with each other is good, even if I've seen the same gags elsewhere and preferred them that way. Nonetheless, this must have been successful for Monogram under the super-efficient direction of William Beaudine, because Howard, Gilbert, and Rosenbloom -- but not Miles -- ganged up in another Monogram comedy the following year.
