The United States learns the Soviet Union is about to send a manned mission to the moon, prompting a rush to send an astronaut to the moon first. Due to the moon program's unpreparedness, a modified Gemini capsule is hastily prepared to carry a single astronaut to the moon. The astronaut will have to survive for up to a year in a specially built shelter until an Apollo mission can rescue him.
