Capsule.

1959: Guy is an experienced British fighter pilot who is in command of Britain's first manned mission to space. He has trained for this for three years at the height of the Cold War and now he is alone in space, suffering Hypoxia, with a malfunctioning capsule. He has limited contact with the UK, some unusual communication with the US and some unorthodox communication with Tyuratam deep in Soviet Russia. Can he get home? Who will help him? Will he make the right choice?
