But he barely gets his family settled when new dangers plague them – a treacherous grizzly bear is on a murderous rampage; angry neighbors covet Cole's property, and an outlaw he once sent to prison seeks revenge.

Jim Cole, his wife Angela, their children Charlie and Gypsy, niece Meg, and friend Sam Potts arrive in a small Wyoming town.

Rancher Jed Curry initially owned the property but lost it to Jim's late uncle in a card game and wants it back.

Jim returns to town the next day and asks Wilhelmina Peterson, who owns the general store, if she knows where he can buy cattle to breed with his prize bull Duncan.

When she goes to a pen to check on the pigs, she finds them all missing or dead; it is the work of Satan, a grizzly bear who invades ranches and kills livestock.

During the night, Satan reaches the Cole place, killing Duncan, causing Sam's mule to flee, and badly injuring the family's dog.

Needing a replacement bull but with no money to buy one, Jim gets a loan from the bank, giving Benson various possessions as collateral.

Charlie jumps out of the tree and distracts Satan, while Dowdy fires at the bear to save the boy, but is fatally mauled.
