When evidence of UFO visits and alien abductions becomes real, a top-secret international agency, SHADO (Supreme Headquarters Alien Defense Organization), is formed, under the direction of Commander Ed Straker. Housed in the underground levels beneath a film studio that hides its activities, SHADO is on the verge of a new detection technology that could turn the tide against future UFO incursions. But the aliens – as yet unidentified – are also aware of this development, and are already taking steps to stop that technology from being deployed. From submarines capable of launching jet fighters, to a moonbase capable of launching space planes, Straker puts all of SHADO’s resources on the highest alert. The prize: SHADO’s first captured alien…and only then does Straker realize that this is but the first volley in a much longer battle for the planet Earth.
