Plot.
Two families in rural Tennessee, headed by patriarchs Laban Feather (Rod Steiger) and Pap Gutshall (Robert Ryan) are at odds with each other. The sons of the two families play harmless tricks on each other but soon the Feather boys decide to kidnap a girl, escalating the rivalry. She turns out to be innocent bystander Roonie Gill (Season Hubley), not the made-up Gutshall girlfriend "Lolly Madonna" that the Gutshall clan had invented to get the Feathers away from their still. As events escalate, Zack Feather (Jeff Bridges) and Roonie fall in love and try to bring the others to their senses, but to no avail. One family busts up another's still; and in retaliation, the sons of that family assault the daughter of the other. After the feud results in a fiery confrontation in a meadow, where one of the Feather boys is fatally wounded and the mother of the Gutshall kin is shot to death, the two families regroup in order to gear up for a final deadly confrontation. With the exception of Sister E Gutshall (Joan Goodfellow), who packs a suitcase and leaves home, the participants engage in battle at the Feather homestead. In the end, all combatants die.
