The Unforgiven

It's 1865 and the southwest is plagued by post-Civil War tensions. But beautiful, winsome Rachel Zachary lives blithely with her mother Matilda on a Texas Panhandle cattle ranch. The Zacharys are a hearty frontier family finally reunited when brothers Ben, Cash and Andy return from a long trip. One day, an old family foe reappears and begins circulating vicious rumors about Rachel: that she was taken from an Indian tribe, clandestinely adopted by the family and passed off as white. Once provoked, the local Kiowa Indians band together to reclaim their lost daughter. Violence ensues and Rachel's betrothed, a feeble-minded white settler, is killed. Outraged, the homesteaders demand to know more about Rachel's birth. After all, why would the Kiowa attack if Rachel weren't of Indian blood? (official distributor synopsis)
