During a storm, a squad of enemy planes attack the fuel depots, causing the Robot Thrower to come out to take them out. Returning to the base is more difficult than expected because visibility is zero and communications are impossible. But when everything seems lost, a light coming from the base guides the boys to the hangar but when the young people explore the laboratory they are disconcerted by the absence of all the staff. Fortunately, Benkei remembers a detail that allows him to discover the truth: it is an exact replica of the laboratory that misled the Getta team. In the meantime, the Demons have penetrated into the real laboratory which was left defenseless and managed to take the Getta ray amplifier with the help of a Demon Robot. The boys manage to escape from the trap before an explosion destroys the fake base; once free, the 3 pilots pursue the enemy and defeat him mercilessly, saving the precious aircraft.
