Mike Goldwing, a plucky, determined 12-year old boy, is the son and grandson of NASA astronauts. His grandfather Frank, a once revered, but now forgotten retired astronaut, lives his days isolated from his family after missing out on his big chance to fly to the moon with Neil Armstrong and Buzz Aldrin as a part of the Apollo XI mission. When an eccentric billionaire sets an evil plan to fly to the moon, steal the moon's vast mineral resources, and destroy the American flag planted by the Apollo XI team, Mike embarks on a magnificent adventure as a stowaway on the space shuttle. Accompanied by his grandfather, best friends Amy and Marty, and a clever chameleon, Mike blasts off to the moon to capture the flag and reunite his family.
