The Earth is under attack. Aliens are harvesting human body parts in order to save their race. To stop this menace, a secret organization is formed to defend the Earth from these attacks. This organization is known as SHADO, or Supreme Headquarters, Alien Defense Organization. / These Earth defenses consist of a Moonbase with fighter spacecraft to intercept the aliens before they get to Earth, a SkyDiver submarine with a launchable fighter should they get by the Moonbase, and various ground based assault vehicles should they get by all the other Earth defenses. / The SHADO operations are coordinated from a movie studio front, known as Harlington-Straker studios. Underneath the movie studio grounds lies a vast operational complex run by the man in charge of the organization, Ed Straker. / Follow Straker and his team as they fight to ward off the alien attack on humanity and their body parts.
