In a rural Mexican village, a powerful and wealthy landowner known only as "El Jefe" offers a $1 million reward for the head of Alfredo Garcia, the man who impregnated his daughter. Benny, a down-and-out American expatriate and piano player in a seedy bar, learns about the bounty from some thuggish bounty hunters. Seizing the opportunity for quick cash, Benny believes he can find Garcia with the help of his girlfriend, Elita, who knows him personally. The pair embarks on a dangerous journey through the Mexican countryside, driven by desperation and greed, encountering various hazards and unscrupulous characters along the way.

As they unravel deep into their quest, tension and violence escalate. Benny and Elita face betrayals and deadly confrontations as they inch closer to their goal. Benny becomes increasingly obsessed with claiming the reward, leading him down a dark and morally ambiguous path. The line between right and wrong blurs as Benny's determination transforms into an all-consuming madness, and he is forced to confront not only external threats but also internal demons. The quest's harrowing toll raises questions about the true cost of vengeance and avarice.
