Convicted by his friend’s glowing account of a play he witnessed the night before, that it must be a real “thriller,” Professor Nicholas decides he will take it in. He phones his wife from the office that he has two tickets for that evening and wants her to go with him. When the thrilling climax to the play comes where the villain chokes the poor girl for not signing the papers, he becomes so excited he makes things very uncomfortable for those around him. Next day he meets a few friends and has a few glasses of light refreshment, with the result that his friends have to bring him home in a taxi. His wife calls him a brute and goes sobbing to bed, while the Professor also sobs and falls asleep in a chair by the fireplace. His mind still obsessed with the play he witnessed, the Professor dreams that he is the villain and his wife is the heroine. After unsuccessfully attempting to force her to sign some papers, he chokes and stabs her, then hides the body under the dining room table. He hears the police coming, but seems paralyzed and offers no resistance when they break in and dramatically arrest him. Without delay, he is sentenced to electrocution. The march to the chair begins at once and he is soon strapped in. While the wardens are awaiting the signal to throw the switch. Satan appears, and after giving the Professor the “Ha-Ha,” sneaks in and turns on the current. Sparks and flames begin to shoot out from around the Professor’s feet and he seems to be burning up. Just then, he wakes up to find his feet in the fireplace and his slippers all ablaze. With a yell, he kicks them off as his wife comes in greatly frightened. He tells her of his nightmare while she gets ice-water and bathes his aching head.
