After China announced a space mission to place its own flag next to the one US astronauts planted during the Apollo 11 mission, few people bat an eyelid. Shortly after this statement, Charlie Stephens, an 81-year-old former filmmaker, is murdered. The incident is made to look like an accident, but why? Going through his father's effects, Gary Stephens—a director of beer and yogurt ads—discovers seven cans of old 35mm film. Dated before the landing, they're identical to the footage NASA claims was shot by the Apollo 11 crew. The US flag is not and has never been in the Sea of Tranquility, and only Tricky Dick and a handful of others knew it. Why was the real nature of the Apollo 11 mission kept hidden? And what measures will be taken to keep the secret buried?
