Panic in the Wilderness (1975)

A hunter disappears when searching for a wounded rogue bear that has been terrorizing the dwellers in a remote area. When the local rangers report that their search for the hunter has failed to locate him and that they haven't the manpower to do much more, the hunter's stepson is persuaded to venture into the wild to find him. With cold weather fast approaching and wilderness perils aplenty, the young man faces a struggle for his own survival which may prove too much for him.
