The Treasure of Lost Canyon (1952)

Young David, orphaned en route to California, falls into the hands of medicine-show rascal Baltimore Dan. Years later, now a trained thief, he's adopted by eccentric 'Doc' Brown, retired miner and pharmacist. Doc and David become fast friends in their scenic outdoor rambles. But when they discover a hidden treasure, the idyllic interlude gives way to more troubles and a strange coincidence.
