When multimillionaire cattleman Jack Mercy dies, his three daughters, half sisters and strangers to each other, discover their father has one last request. According to his will, the trio must live on his ranch together for one full year in order to claim their inheritance. The gals know this forced family reunion isn't going to be smooth sailing, but they don't expect to go head to head with someone out to sabotage them. Turns out Daddy dearest may have left a few enemies behind when he checked out, and it's up to his unsuspecting offspring to deal with his mess, or they'll lose out on the money. John Corbett, Charlotte Ross, Ashley Williams and Diane Ladd star in "Nora Roberts' Montana Sky."
