Guy, an experienced fighter pilot has a lofty dream; to be the first Briton who sets foot in space. For that, the Guy has trained intensively for three years. His dream is the time that it is sent on a mission aboard Hermes. However, because of a failure, after the five planned rotations, Guy remains locked in a capsule. With limited contact with people on the ground, suffering from the effects of hypoxia, Guy is forced to find a way to take the capsule back to earth or risk to remain lost in space forever.
