When the British-American Rocket Group sends an experimental manned spacecraft into outer space they soon lose contact and it crash-lands over two days later. But as the scientists force entry to rescue the three-man crew, they find to their horror only one astronaut and two empty space-suits.

Directed by BAFTA winner Val Guest (The Day the Earth Caught Fire, The Abominable Snowman), it stars Oscar nominee Brian Donlevy (Destry Rides Again, The Big Combo) and Richard Wordsworth (The Curse of the Werewolf, The Revenge of Frankenstein).

Witness the cold realism, creeping terror, and groundbreaking storytelling that set the standard for British sci-fi.
