Porky Pig purchases a new home from a real estate agent, which turns out to be an old Gothic-style house: the sort featured in murder mysteries and ghost stories. His cat Sylvester is frightened of the creepy-looking place, but Porky finds it “quaint” and “peaceful”, and looks forward to his first night there. Sylvester is already holding onto the bottom of Porky’s coat, unwilling to let go, when he is spooked by a bat and jumps inside the coat. Porky chastises him for being afraid of the bat and says he is going upstairs to bed, Sylvester can go sleep in the kitchen. Unknown to Porky, Sylvester clings to him all the way to the bedroom and into bed. When Porky discovers him in the bed, he kicks him down the stairs, telling him to stay in the kitchen. Before long, Sylvester sees that the house is overrun with mice; killer mice, in fact (one wearing an executioner’s hood and carrying an axe, the rest looking like the Chuck Jones-created characters Hubie and Bertie), who are just in the process of carting off the previous owners’ cat (resembling a grey-furred version of Sylvester) to the chopping block. Already shaking with terror, Sylvester’s eyes go pin-point with fear and his heart visibly pounds in his chest. He races upstairs and into Porky’s nightshirt. Porky begins scolding Sylvester, who interrupts this by demonstrating (in mime) what occurred downstairs. Porky criticizes the “ridiculous acting” and orders Sylvester back to the kitchen. Too frightened to comply, Sylvester pulls a gun from a dresser drawer and prepares to shoot himself in the head. Porky disarms him and can’t believe how desperate his cat is.
