Jim Guthrie (Dana Andrews) returns to town three years after being falsely accused of murdering Carter Mastin (Richard Webb). Jim finds that his old friend Ben East (Stephen Elliott) is now the sheriff. In a flashback, Jim recounts his near-lynching by a mob convinced he had shot Carter in the back. Laurie (Donna Reed), Carter's sister, who was planning on marrying Jim, disrupts the lynching, and Jim narrowly escapes. He still bears a neck scar from his ordeal. Ben gives Jim three hours to find the true killer. Through confrontations with several of the men who had been eager to hang him, Jim is led to the guilty man.
