David Freeman (Joey Cramer), a 12-year-old boy, is mysteriously abducted by an alien ship and returns to Earth eight years later, still only 12. He now possesses great navigational powers that enable him to fly his space ship anywhere he desires. Along with the robotic Commander Max (voiced by Paul Reubens under the name Paul Mall) and Mascot Puckmarin, the boy encounters an adventure of extraterrestrial proportions.
