A group of men, including a lieutenant and soldiers named Simmons and Pickard, were stranded on Venus, a planet where it rained perpetually. The rain was so intense and relentless that it drove the men to the brink of insanity. They were trying to reach a Sun Dome, a shelter that provided warmth, food, and respite from the rain.
We'll be at the other Sun Dome by four this afternoon.
They reached one Sun Dome, only to find it destroyed by the native Venusians. One of their group, Pickard, went mad and was killed by Simmons to prevent him from becoming a burden.
Simmons later committed suicide, leaving the lieutenant alone.
Can't you hear anything? You go on. I'm tired. I don't think the Sun Dome is down this way.
The lieutenant, driven to desperation, considered walking into the sea to end his suffering. However, he spotted another Sun Dome in the distance. He reached it, finding it intact with food, dry clothes, and a synthetic sun providing warmth. The sight of the sun and the relief from the rain brought him immense comfort.
