Voyager One crosses paths with the Moon, and its creator helps to stop it before its lethal nuclear wake wipes out Alpha. However, an alien fleet from a planet destroyed by the waste comes looking for the probe and its creator seeking revenge.

Tony Cellini, the only survivor of a deep-space probe, claims that an alien creature consumed his other three crewmen… and now Moonbase Alpha is approaching the same graveyard of alien spaceships.
