As outlaw Jake Leach lies dying in a deserted cave, he writes a desperate letter to his brother, Tom, a US Marshal. Jake has double-crossed his boss, the violent and vindictive Quirt Evans, stealing eighty thousand dollars' worth of government-owned gold coins from his own outlaw gang in hopes of redemption.
By the time Tom Leach receives Jake's letter, Jake is dead; however, the outlaw left clues that will lead Tom to the stashed gold coins. Jake's final request is for Tom to return the coins to their rightful owner. Maybe then his soul can rest in peace. Tom has his hands full, though, keeping the peace as greedy marauders threaten new settlers in untamed land.
In order to discover Jake's lost gold, Tom must fight his way through outlaws on the wild frontier. As Jake's clues become more convoluted and Quirt's gang moves closer, Tom is forced to forget his lawman ways and act the outlaw himself. Otherwise, he'll end up dead like Jake, and his brother's last indiscretion will linger in eternity.
