In 1938, William and Susan Travis visited Mexico as tourists. They took great joy in the novelty of experiencing a simpler time; a stark contrast to their future world where chaos and war were prevalent realities. They loved indulging in things considered vices in their time, including alcohol and cigarettes.
One day, they came across a man named Simms who seemed strangely familiar with their habits, such as leaving the trouser legs down.
Simms confronted them, revealing their identities and the fact that they were from the year 2155 and had escaped a horrific war.
We should never have tried to escape. My God! said William, he's coming over. Let me do the talking.
Simms, also from 2155, had been sent through time to retrieve them. William agreed to return to the future if Susan could remain in the past. Later, William managed to kill Simms by running him over with a car. They then joined an American film company, thinking it to be a safe shelter. However, the company was constituted entirely of Simms' colleagues.
So the Searchers, let's call them, spare no trouble or expense to find, capture, and take home the man and wife, once they get them totally alone, in a hotel room, where no one can see.
William and Susan were surrounded and captured in a beam of blue light. After that, their existence in the era suddenly vanished, leaving behind only stacks of liquor and cigarettes.
