During a routine test flight above the deserts of the Southwest, ace
pilot HAL JORDAN has a too-close-for-comfort encounter with a UFO. His
jet takes a nosedive, but before HAL bites the dust, a gigantic green
hand appears, grabs the aircraft, and prevents the crash. The mysterious
UFO reveals HAL'S alien rescuer who possesses an amazing green ring of
untold power. What does HAL do when the alien offers him the ring, and
announces that the human pilot is now the new GUARDIAN OF EARTH?
