Someone found out about a painting that Albert Bierstadt left in Estes Park in the 1870s. Someone who's willing to break into summer homes looking for it, and murder anyone who gets in the way. Many of those homes lie inside Rocky Mountain National Park, which means it's up to Ranger Tim McIntyre to find out who the searcher is, why they will kill for it, and where the Bierstadt painting's hidden. Luckily the park ranger can enlist the assistance of his glamorous detective friend, Miss Vi Coteau"--
