His dream is to recover equipment left on the Moon during Apollo Program missions for he believes the salvage value will make it a worthwhile venture. He invites a former astronaut Addison "Skip" Carmichael (Joel Higgins), who'd been fired for being a daredevil, and Melanie "Mel" Slozar (Trish Stewart), a fuel and explosives expert who'd been working as a movie stunt coordinator, to assist him in this effort.
