When a pearl with a sinister reputation for causing misfortune to its owners is stolen from a museum by a master criminal because of Sherlock Holmes’ show-boating, he is naturally obliged to find it. Soon, he learns of a series of brutal murders that seemed to have been commited by a malevolent man mountain known only as the Creeper. Now, Holmes must deal with the seemingly overwhelming menace of this man and his boss in order to retrieve the pearl.

Boss Spearman, Charley Waite, Mose Harrison and Button freegraze their cattle across the vast prairies of the West, sharing a friendship forged by a steadfast code of honor and living a life unencumbered by civilization. When their wayward herd forces them near the small town of Harmonville, the cowboys encounter a corrupt sheriff and kingpin rancher who govern the territory through fear, tyranny and violence. Boss and Charley find themselves inextricably drawn towards an inevitable showdown, as they are forced to defend the freedom and values of a lifestyle that is all too quickly vanishing. Amidst the turmoil, life suddenly takes an unexpected turn for the loner Charley when he meets the beautiful and warm spirited Sue Barlow, a woman who embraces both his heart and his soul.
