"Bloodbrother Bear" is set in the mountains of northern California in the late 1940s. A mountain man, hired by a natural history museum to collect specimens, encounters a "rogue" bear, a former camp raider from a national park who has been captured and released into the wild. The bear has no fear of humans or their campsites, and in fact feels an affinity for humans. The man feels some empathy with the bear as well, until their joined fates become a duel for survival.
