"Her Pilgrim Soul" is the first segment of the twelfth episode from the first season (1985–86) of the television series The Twilight Zone. It is about a scientist named Kevin whose holographic projector manifests a newborn and rapidly aging woman named Nola. The title comes from "When You Are Old", a poem by William Butler Yeats, a few lines of which are recited by Kevin just before Nola's farewell. This story was made into a one-act stage musical by Alan Menken and paired with James Tiptree, Jr.'s "The Girl Who Was Plugged In" as a stage production titled Weird Romance: Two One Act Musicals of Speculative Fiction. Plot Kevin and Dan are scientists designing a holographic projector. One day, the device generates images of a human fetus which are not in the stored data. When they return the next day, the fetus has already matured into a young girl, who introduces herself as Nola Granville. Nola lived in Westchester County, New York during the early twentieth century. Dan calculates she is aging at a rate of ten years each day. They debate over whether or not Nola is a human soul somehow integrated into their hologram generator. Kevin's marriage has already been strained by his spending all his time at the lab and his repeatedly postponing their plans to have children, and after he falls in love with Nola, he separates from his wife Carol so that he can remain by Nola's side 24 hours a day.

Nola relates meeting and falling in love with Robert, who her father objected to because he was Jewish. She becomes convinced that she has manifested in the projector to take care of some unfinished business, and asks Kevin to help her recall what it is. He searches for surviving acquaintances of Nola in hopes they may have the answer. During the fifth day of studying Nola, she relives a miscarriage. Days later, Dan finds a surviving friend of Nola's, who tells him Nola died from the miscarriage, at the age of 35, and that Robert became despondent afterwards. Kevin is left wondering why Nola is still around when her real life ended when she was decades younger. Nola uses a voice modifier to impersonate Kevin and tell Carol to
