Marshall Big Jim Cole (Clint Walker) decides to retire from law enforcement when he learns that he has inherited land in Wyoming from a relative. He moves his family and former deputy Sam (Don Haggerty) with him when he goes. When they get there, he and his wife Angela (Martha Hyer), son Charlie (Kevin Brodie), daughter Gypsy (Victoria Paige Meyerink) and his niece Meg (Candy Moore) find that the ranch has been unattended to and is need of a lot of work.
As the crew sets about to restore the ranch, they soon discover that they have more problems yet to deal with. Big Jim finds that his neighbor Jed Curry (Keenan Wynn) used to own the property and wants it back for his two sons (Sammy Jackson and Ron Ely), and will do anything to take the land back. Making matters worse, the family also discovers that there is a huge grizzly bear on the loose that is killing livestock and people alike.
Now, Big Jim doesn't know which problem to handle first. With Jed constantly demanding that he will, at all costs, have his land back and Big Jim repeating over and over that he will never leave the two begin a rivalry that his family fears will only end badly. With the grizzly bear in the midst, and all their lives at stake Jim is wondering if he has bit off more than he can chew. And even worse, wonders if the grizzly bear is less of a threat than his demanding neighbor.
Between restoring the ranch, trying to rid the town of the grizzly and staving off Jed Curry and his troublesome sons, Jim has to make some pretty big decisions that he knows will affect the safety of his family. Jim knowingly puts his life at risk in a final attempt to make his home his own and keep his family alive.
