I quattro cavalieri del terrore / 1957

An imprisoned gunfighter must scatter to elude the authorities. Outlaws Bob Ford (Robert Vaughn) and Vic Rodell (Stephen McNally) are nabbed, but the governor offers them amnesty in exchange for their help in bringing Jesse and his brother Frank (Douglas Kennedy) to justice. Peggie Castle and Barton MacLane also star in this tale of the Old West's most famous traitor.
