Theatrical Release Information:
Five Card Stud

Dean Martin and Robert Mitchum play deadly adversaries in this curious mixture of the western and mystery genres. During a poker game in Rincon, Colorado, a stranger in the game is lynched for cheating. One of the gamblers, Van Morgan (Dean Martin), tries to prevent the lynching but is rebuffed and promptly leaves town. Soon a gold rush hits Rincon, bringing all manner of men and women -- including self-ordained preacher, Rev. Jonathan Rudd (Robert Mitchum) and brothel madame Lily Langford (Inger Stevens). Learning that two of the men in the poker game have been murdered, Van returns to Rincon to find out why. Once in town, Van is diverted from his investigation by the attentions of Lily and of Nora Evers (Katherine Justice). But when two more of the poker game's participants are killed, Van must spring into action to track down the killer. ~ Paul Brenner, All Movie Guide
