In this episode, a man finds his hometown is suddenly inconsistent with his memories of it and begins experiencing irrational urges to commit murder, two mysteries which together lead him to an unpleasant discovery about his identity.

Though he met Jessica only four days before, they have already set a date for their wedding, and Alan is taking her to his hometown of Coeurville to meet his aunt Mildred, who raised him.

When they arrive, almost everything in the town is as Alan remembers, but another man is living in his house, the university where he was employed is gone, and all of the people he knew are either said to have died years ago, or else there is no record that they ever existed.

In the place where his parents were buried, he instead finds a tombstone with the name "Walter Ryder"; seeing this name seems to trigger a repressed memory in Alan.

The driver applies the brakes in enough time that Alan is not gravely hurt, but a deep cut in his wrist is bizarrely not bleeding.

Walter explains that Alan is an android he developed using funds from a calculator he invented, using help from some of the world's greatest scientists, and his own self-professed genius.

After the struggle, the survivor goes to Jessica and asks her to forget about his strange behavior of the past couple of days, saying that the nightmare is over and he will tell her what happened someday.

In the final scene, it is revealed that the survivor is Walter and that Alan's broken form lies amid the wreckage of the laboratory.
