Proud warrior Navajo Joe (Burt Reynolds) is the only man left alive when outlaw Marvin Duncan (Aldo Sambrell) and his brutal gang destroy his village. Riding into a nearby town of white settlers, Joe announces his plans for vengeance, but the townspeople fear Duncan's retribution too much to stand behind him. In the course of his one-man battle against Duncan's small army for control of the town, Joe falls for beautiful maid Estella (Nicoletta Machiavelli).
