World Without End

In March 1957, commander Dr. Eldon Galbraithe (Nelson Leigh), engineer Henry Jaffe (Christopher Dark), radioman Herbert Ellis (Rod Taylor) and scientist John Borden (Hugh Marlowe), are returning to Earth from the first spaceflight, a reconnaissance trip around Mars. Suddenly, their spaceship is somehow accelerated to incredible velocities, and they are knocked unconscious. Their ship crash lands on a snow-covered mountain. When they venture out, they discover that they have become victims of time dilation and are now in the future.
