Execution

"Execution" is an episode of the American television anthology series The Twilight Zone. In 1880, a man named Joe Caswell is about to be hanged for murdering a civilian. But as the noose tightens around his neck, he suddenly appears in the modern lab of Professor Manion. Manion explains that he used a time machine to randomly pluck Caswell from the past.

Caswell then tries to escape onto a busy street, but becomes so overwhelmed by the lights and the noise that he returns to the lab. Seeking the scientist’s aid, he realizes that his blow has killed Manion. Then a thief, Johnson, breaks into the lab.
