In 1950’s West Texas best friends Tim and Hect happen upon an abandoned auto junkyard. Hunting rabbits loses its appeal for a game of war with their .22 rifles. The fun abruptly ends as their boyish prank goes awry. They set fire to an empty shack which turns out to be home to a hapless drifter, or so they believe.

Hect has the idea to set fire to the shanty. Tim readily agrees, although he thinks the target is a wasp nest in a mesquite bush. Hect fills a bottle with fuel from a wrecked truck and hurls the Molotov cocktail at the shed. The sun-dried wood bursts into a fireball. Shocked at his friend’s aim, Tim gapes as a blazing figure peers out a fiery window. He and the human torch gaze at one another for a long moment until sirens from town interrupt. The boys, believing their prank will land them a seat on “Sparky,” the pet name for the electric chair in Gatesville Prison, become fugitives from the law.

Armed with a forehead-slapping sense of naiveté, the two run into the harsh desert. Because of pampered lifestyles, they could not be less prepared to endure hunger, an unforgiving sun, life on the road, con artists, wily street people, and a world of poverty and slums, plus the mean streets of Juarez, Mexico.
