March 1965. In the heat of the Cold War, the USA and the USSR are competing for supremacy in space. What both superpowers aim for in this race, is to be the first to have a man walk in outer space. To accomplish that, no price is too high and no risk is too great. Now it’s up to the unlikely duo of a seasoned war veteran and a hot-headed test-pilot to fulfill this mission. Two men in a tiny spaceship, without proper testing, facing the complete unknown. They were supposed to do what no man has done before—and no man imagined what would happen next.

Their plans are complicated by a hurricane headed towards the launch site—and a shrinking air supply in the astronauts' capsule.

In the near future, a space station dubbed Earth II is built for the purpose of scientific research and world peace. However, that peace is shattered when the Chinese send up a nuclear bomb that is orbiting just a few miles away from the station.
