Actor Bull Montana (a former professional wrestler) played Ferry, the Ape Creature, in the film. He later went on to play the ape-man in the 1925 Willis H. O'Brien classic The Lost World, which was also written by Marion Fairfax and starred Noah Beery's actor brother Wallace Beery.^[5]

Helen Allen (Agnes Ayres) inherits her deceased father's newspaper, but someone is trying to sabotage the business. She gets a job at the company under a false name, so that she can detect exactly who is trying to ruin her. She winds up instead investigating a number of gruesome murders with the help of a reporter named Kirk Connelly (Pat O'Malley).

One of the victims was a scientist named Dr. Ord (Noah Beery). Helen learns that Dr. Ord had been involved in an experiment in which he transplanted the brain of a criminal into the body of a gorilla. The beast turned on him and then went on a killing spree, hunting down and murdering all of his old enemies. In the end, Helen also finds out who it was who was trying to ruin her newspaper.
