In their latest quest for a business venture, a treasure map is discovered. We join Lum and Abner in a field, with Abner getting fed up with the lack of results.
Lum renews his efforts at reading the map, but both Cedric and Abner are too worn out to dig any more. The disalusioned Abner pokes fun as Lum gets busy with the business end of a shovel. Cedric gets confused as he patiently listens to Abner tell a story about a former resident of Pine Ridge.
Suddenly, Lum reports hitting a box. Is it the gold and jewels they expect? Can they break open the rusty lock? Will they become wealthy from the discovered treasures?
