Ruthless cattle baron Tad McDermott and his partners have hired a band of fifty killers to wipe out newly-arrived homesteaders and their families. When rancher George Bingham is murdered, his son, Jerry, travels from New York to find out who's responsible. Joined by feisty homesteader Jill Carmody, Bingham soon discovers a web of corruption and systematic murder that has made a mockery of the law and endangers the opening of the frontier. And there'll be hell to pay, and blood to spill.
