Lonegan rides into the town of Gultree on a warm afternoon, one of dozens of little wild west settlements never able to warn each other about him in time. He's perfected his performance. First, he sets up his medicine cabinet, tricking townspeople into wanting to purchase his wafers. Inevitably, Gultree's preacher arrives to accuse Lonegan of being a snake oil salesman. Lonegan promises his wafers really do work, and to prove it, he'll only accept payment for them after the town's inhabitants have seen that they do. He offers the preacher a bag of wafers to serve at communion and promptly gets himself arrested. While Lonegan sits in jail, a beautiful woman named Annie approaches him, angry at him for selling her aging father remedies she knows cannot be real. Lonegan invents a friendship with her and convinces the sheriff to arrest her. Safe within their cells, Lonegan and Annie don't witness the horrors his wafers unleash during the preacher's church service. The townpeople become zombies who devour one another, until they are the only two left alive. Lonegan leaves his jail cell and frees Annie as well. Then he sets about collecting everything in the town he could possibly want. Horrified by Lonegan's vocation of wiping out entire towns, Annie commits suicide by shooting herself. Lonegan returns to Annie's bakery to look for a cake she might've made and encounters her father, still shambling about, who waves a fistful of stolen wafers at Lonegan. Disturbed, Lonegan rides off into the desert without searching the rest of the town. When he stops to eat the cake, he's horrified to discover his own wafers baked into it, courtesy of Annie's dad.
