When Apollo astronaut Gene Cernan stepped on the moon in December 1972, he left his footprints and his daughter's initials in the lunar dust. This film takes Cernan back to the launchpads of Cape Kennedy to tell his story of burning ambition, fulfilment, love and loss. Using a wealth of rare archive, home movies, scrapbooks and interviews, it recounts how Cernan's burning ambition carried him from a quiet Chicago suburb to the spectacular and hazardous environment of space.
