Having inherited a huge cattle ranch from his late father, Will Keough (Fred MacMurray) wants nothing more than to tend to his work and live in peace, but this is made impossible by the tense situation in his own household. Will's two younger brothers, Bless (Jeffrey Hunter) and Hade (Dean Stockwell), are as different as night and day: Convinced that he was responsible for the death of his father, Bless refuses to use a gun, and is thus branded a coward; conversely, Hade is wild and reckless, literally an accident waiting to happen. Exacerbating the situation is the brothers' grim and merciless mother (Josephine Hutchinson), who has instilled most of Bless' guilt feelings, and Will's sweetheart Aud Niven (Janice Rule), who finds herself drawn to the sensitive Bless. Ultimately, there will have to be a showdown...but who among the Keogh siblings will survive?
