When Reg Thompson, an R.A.E Pilot and Instructor, survives an early attack against the apparently invulnerable City Destroyer, he retreats into the Saudi desert and hooks up with an ill-organized and fractious force of freedom fighters from the armies of several nations, including Khalid, a Saudi pilot; the beautiful Fadeela, Khalid's sister; and Faisal, the Saudi prince who is their leader. When Faisal's decision to ignore American help almost loses the war, Reg and Khalid must team up to beat the alien survivors and destroy the secret cache of biological weapons the invaders plan to unleash upon humanity. It's a hard-hitting, action-packed techno-adventure with furious rivalries, suicidal heroics, and a heart-stopping race against time to save our planet.
