Some Mexican outlaws are pretending to be Apaches as they wreak havoc across the west.

Their despicable leader Diaz has the help of two fugitives—who have it out for Slocum ever since he put them in jail for robbing a beautiful young schoolmarm. And Slocum owes her for teaching him a lesson he won’t soon forget. So he’s packing lead with a vengeance—and is ready to send Diaz and his men to their graves…

You can fool the law, but you can’t trick Slocum.
