Captain Woodrow Call, now retired from the Rangers, is a bounty hunter. He is hired by an eastern rail baron to track down Joey Garza, a new kind of killer, only a boy, who kills from a distance with a rifle.
Woodrow breaks off from his posse to pursue Mox Mox while his men try to capture or kill Joey Garza. Meanwhile, Lorena searches for Pea and Joey's mother Maria tries to help her son elude the law.
