Director: Val Guest
The first manned spacecraft, fired from an English launchpad, is lost from radar before roaring back to Earth and crashing in a farmer's field. The rocket is found to contain only one of the three men who took off in it; and he is unable to talk but appears to be undergoing a torturous physical and mental metamorphosis.
