A rocket expedition from Earth lands on an uncharted planet to be greeted by a seemingly empty city. As the humans begin to explore, they realize that the city is not as empty as it seems. The city was waiting for the arrival of humans; the contingency plan of a long dead civilization, put in place to take revenge upon humanity after their culture was wiped out with biological weapons by humans long before recorded history. Once the city captures and kills the human astronauts, the humans’ corpses are used as automations to finalize the city’s creators’ revenge; a biological attack on the Earth.

A couple from the future tires of the war in their modern lives, so they go on a vacation to the more serene past in an attempt to escape with the help of a company called Travel in Time, Inc. They go to Mexico in 1938, but are pursued by a government agent who forces them to come back to 2155.

Two men in a spaceship are discussing how empty and cold space is. The first man is a little bit insane and keeps asking questions about how there is nothing sure in space and there is no night or morning. He refuses to believe anything about reality without sufficient evidence and soon becomes skeptical of everything he cannot directly experience. He said that he doesn’t believe in stars because they are too far away. The second man is wandering about the ship when he learns that someone has left the ship, and it is the first man. The first man is still talking to himself and has killed himself by letting himself fly freely through space.
