When Bob Hart, a widowed police detective trying to raise a rebellious teenage daughter, inherits a Montana horse ranch, he jumps at the opportunity to leave Los Angeles for the open range. Soon after arriving, Bob accepts the position as county sheriff and discovers that the seemingly bucolic countryside is far from tranquil. His problems include wolves who attack his stock, ruthless developers trying to take over the town and a female veterinarian with a chip on her shoulder, while trying to build a new home.
