While on the run from Rurales in Mexico, Lou Prophet stops at the familiar desert town of Chisos Springs. Except now it’s called Moon’s Well. And it appears that more than the name has changed. It’s being controlled by the scoundrel Mordecai Moon, who even charges people for water. Lou Prophet won’t stand for such shady business, but he’s never made an enemy like Mordecai...
 
When Mordecai has Lou beaten and sends him into the blazing desert tied over his horse, matters go from bad to personal. Rescued by an old friend and business partner, Lou is ready to end Mordecai’s reign of terror. And with the outlaw’s own girlfriend straddling sides, Lou will make sure he goes out with a bang.
