Having forsaken westerns for detective melodramas in Dial Red O, William "Wild Bill" Ellliot continues in this vein in Sudden Danger. Elliot is cast as detective lieutenant Doyle, who at present is investigating the alleged suicide of a clothing manufacturer. Doyle suspects that the victim was murdered, and that the perpetrator was the dead man's blind son, Curtis (Tom Drake). Hoping to clear himself, Curtis begins searching for clues on his own, and by fadeout time he and Doyle have cornered the actual killer. Though obviously made in a hurry, Sudden Danger is elevated by better-than-usual scripting and a well-chosen supporting cast.
