In New Orleans, discharged army Captain Vance Colby learns of his father's killing done by three local Creole gents at a card game, and he sets out to punish the killers.
Army officer Dale Robertson arrives in New Orleans to settle his father's estate in antebellum New Orleans. His father had been a gambler, and an honest one, but he is shown evidence that he was cheating and killed for it by local aristocrat Kevin McCarthy, whose beautiful sister, Lisa Daniels, RObertson has rescued from a rainstorm. Despite her beauty, RObertson begins his Monte-Cristo-like course of vengeance. He is aided by riverboat captain Thomas Homez, and his daughter, Debra Paget, at her most sultry.
It's one of the series of handsome Technicolor 'shaky A' productions that Robertson starred in in this period. Robertson shows off some athleticism in a final epee duel with McCarthy. There's lots of careful camera composition by cinematographer Lloyd Ahern Sr. to cover the fact that Robertson is dueling with a stuntman.
