Tales from the Crypt (1989)

S6E7 Staired in Horror

Clyde, on the run from the law, seeks refuge in a house inhabited by an elderly woman. One evening, he encounters a stunning woman upstairs, only to realize she's the same person. She reveals that her husband cursed the house after discovering her infidelity, forcing her to remain upstairs to preserve her youth. If Clyde ascends as well, he, too, will face the same fate. When the police show up, he decides to go upstairs to alter his appearance but soon finds himself growing weaker, while the woman transforms back into a helpless infant, unable to do anything but crawl.
