Reprisal!

New ranch owner Frank Madden, half Indian but posing as white, arrives just as an all white jury finds the three white Shipley brothers who lynched three Indians innocent. There is soon trouble between Frank and the Shipleys who are using Frank’s land to graze their cattle. When the brother of one of the Indian victims kills a Shipley, Frank is accused and put in jail. The Shipleys then organize a lynch mob and head for the jail.
