On his way to Larned, Matt, feverish, spends the night at an abandoned shack. When he wakes up after losing a day, a recently released convict who swore to kill Matt, is himself found against a wall, dead, unarmed, shot twice, and the murder weapon appears to belong to the marshal.

Matt finally catches up to killer Charlie Hacker in Mexico, and has to make a deal with the greedy Mexican police to get Hacker back to the border, with revengeful Mexican bandits in pursuit.
