John Grady Cole, a 16-year-old dispossessed Texan, crosses the Rio Grande into Mexico in 1949, accompanied by his pal Lacey Rawlins. The two precocious horsemen pick up a sidekick--a laughable but deadly marksman named Jimmy Blevins--encounter various adventures on their way south and finally arrive at a paradisiacal hacienda where Cole falls into an ill-fated romance.

Two men working as ranch hands in New Mexico in 1952 find their lives and values changed forever.
