The boys from Pine Ridge get quite an education when the town finds itself in need of a new school teacher. The candidate they hire is eminently qualified - and not at all what president of the school board, Lum Edwards, had in mind!

Professor Sloane, tireless in the pursuit of knowledge, spearheads ambitious plans for an observatory, a rocket ship, and a trip to Mars - manned by none other than Lum and Abner! With financial backing from the unscrupulous Squire Skimp, the duo declares themselves "scientifics" and set their sights on the stars.
