While on a road trip through a desert, mild-mannered high-school teacher Ralph Hinkley is greeted by extraterrestrials, who present him with an extraordinary red flying suit that imbues him with uncanny powers. Learning of the suit, high-strung FBI agent Bill Maxwell convinces Ralph to use the suit to help him fight crime. Unfortunately for Ralph, he lost the instruction book and must learn how to use the suit's powers by trial and error, often with comical results.
