His pet cat Sylvester is frightened by the creepy-looking place, but Porky finds it "quaint" and "peaceful" and looks forward to his first night there.
Suddenly, Sylvester sees that the house is overrun with murderous mice who are in the process of carting off the previous owners' cat to be decapitated by a mouse wearing a black hood and holding an executioner's ax.
Too frightened to comply, Sylvester pulls a gun from a dresser drawer and prepares to shoot himself in the head rather than face whatever fate the mice have in store for the pair.
Sylvester proceeds to do so, himself barely awake and walking on thin air, as the pole springs the bed back into the room.
Descending the staircase, Sylvester sees the hooded mouse roll a bowling ball down the banister, targeted directly at Porky, who has reached the bottom.
Meanwhile, at the base of the staircase, Sylvester teeters and then falls to the floor unconscious after his head is flattened by the bowling ball intended for Porky.
Over the next few scenes, as he lifts Sylvester, carries him to the kitchen and puts him in the basket, an oblivious Porky barely escapes many attempts, via several tools and weapons, by the mice to kill him.
After a few seconds of silence, Sylvester looks in the kitchen and sees the mice parading as they did earlier with the other cat, only now it is Porky who bound and gagged and on his way to be decapitated.
As he rests to catch his breath, his conscience (a miniature Sylvester wearing a wizard's robe and carrying a star-tipped wand) appears with an easel.
The mouse then yanks off his hood, revealing that he has transformed into a Lew Lehr caricature wearing a Napoleonic-era bicorne hat.
