What's a life worth? $300, maybe. Half-Mexican Corbin Molina lost a hand during the Civil War but he has adapted. Now he's on a mission to Walkerville. On the way, he prevents a train robbery and finds an old friend. Corbin always carries $300, which is significant, since that's what he was a paid as substitute soldier for the Union. When Corbin starts asking questions about Walkerville's law and administration, he discovers that the Walker family, who seem to have bought and paid for loyalty and position, dominate the townspeople. Inevitably, Corbin's questions attract plenty of trouble. And his past emerges to confront him during a tense showdown that threatens not only him but also his newfound love.
