***SPOILERS*** It's when the master of the house Mr.Earlton passed away that all his relatives as well as servants were gathered to hear his will read with his daughter Ruth Earlton,Vera Reynolds, getting the lion share of his holding including the house itself. That's when things started getting a bit weird with the pet monkey Yogi that her father kept locked up in the basement getting very excited and unnerve by just seeing or even picking up Ruth's scent. It's Ruth's late father a follower of the Darwinist theory of the Evolution of man descending from apes or monkeys was using Yogi in his experiments. It was Yogi who developed a strong dislike of Ruth when she, in being afraid he'd grab her arm, didn't hand him over a banana as a treat.
It's soon become apparent that Yogi is on the loose in strange things happening at the house that's connected to him. Even though he never once left his cage when these things were happening. Even when Ruth as well as her uncle the wheelchairs bound Robert Earlton, Sheldon Lewis, were almost strangled by what looked like a hairy and monkey-like hand while asleep in their bedrooms. With all the attention on the maligned monkey Yogi it turned out that the butler or monkey's attendant Hanns Krug, Mischa Auer, and his mom the house maid Mrs. Krug, Martha Mattox, were behind all this monkey business to ice out or do in Ruth from getting her share of her father's money and property.
****SPOILERS**** It's soon found out that Hanns is actually Ruth's step brother or first cousin, it's not quite sure which one he is,who together with his mom Mrs. Krug feel that they were left out in the cold by the old man leaving them almost nothing, but $50.00 a month for life, in his will. Hanns in trying to murder Ruth and make it look like Yogi did it, by using a Halloween gorilla hand or paw,in trying to murder her strangled his mom, who was sleeping under the covers, by mistake. That has a very unstable Hanns go completely banana's and attempt to do the same to his what turned out to be father the crippled Robert Earlton without much success. In the end completely out of his skull Hanns drags Ruth down to the basement and tries to get Yogi to do her in who turns out to be a lot smarter then he or anyone else thought he was. And instead Yogi put the squeeze or end on Hanns' insanity by, in what he attempted for Yogi to do to Ruth, ringing his rotten neck.
