The first of the Superman cartoons filmed under the aegis of Famous Studios, Japoteurs begins with a Daily Planet headline letting the audience know that the U.S. has developed the world's largest bomber plane and that it will soon be making a test flight. The paper's top reporters, Clark Kent and Lois Lane, are allowed to take a tour of the plane prior to its flight, and see that, in addition to its other features, it can also serve as an airstrip for launching smaller planes. Lois stows away after the tour is over, but she's not alone -- a number of Japanese spies have also stolen aboard, and they hi-jack the ship soon after it takes off. The spies plan to fly the plane to Tokyo, but Lois manages to radio for help, and Superman flies to the rescue. Upon his arrival, he learns that Lois has captured and the spies threaten to release her from the bomb bay doors if Superman doesn't leave. He obeys, but the spy releases Lois anyway, but Superman saves her. Beaten, the agents have set the controls so that the bomber will crash into Metropolis, but Superman uses his massive strength to catch the plane just in time.
