Low-budget British sci-fi drama. The film follows astronaut Guy Taylor (Edmund Kingsley) as he becomes the first British man in space. During the Cold War, Guy sets off to orbit the Earth but, not long after, his capsule begins to malfunction. With little contact with Earth and his oxygen supply rapidly depleting, Guy can only hang tight in his claustrophobic capsule while others try to work out how he can make it back home safely.
