A father and daughter on the mend pack up their memories of the city for a new life and a new beginning in the open wilds of the Montana countryside.

Widowed Los Angeles cop and single father Bob Hart is as accustomed to the wild streets of the city as his skateboarding teenage daughter Madison is to its concrete valleys. They’re both in for a culture shock when Bob discovers that his estranged father, a mustang rancher and sheriff of a small Montana town, deputized him before he passed away. As interim sheriff, Bob has no recourse but to pack it all up and rescue the family ranch now in danger of being sold to the highest bidder. For urban daredevil Madison, this means trading in her board for cowboy boots. When they arrive in a place called Hope, Bob realizes how much has changed since his days there as a boy.

Main Street is slated for razing by developer Cody McMichael in a bid for a shopping mall. The Hart Ranch and its twenty mustangs are endangered as well. A conservationist has obtained a court order to seize the herd, and Cody’s set to take over the vulnerable property. Saving a forty-year-old family legacy is Bob’s main concern. But when the threats against the town and the ranch escalate, Bob has to rally all the support he can to make his dream for a new life come true.

Stars: Richard Thomas, Nancy McKeon, Joseph Culp and Halee Hirsh
