Cardsharp Edmond O'Brien gets more than he bargained for when he links up with con artists Lizabeth Scott and Alexander Knox. The trio plot to fleece a wealthy couple out of ten million dollars by having O'Brien pose as the couple's long-lost son. When the husband (Griff Barnett) refuses to change his will, Scott and Knox plan to bump him off. O'Brien may be a crook, but he's no murderer, so he balks at the plan and confesses the scam to the elderly couple--prompting Knox to add O'Brien to his list of potential victims. When Scott decides to pull out of the plan as well, Knox is run out of town, leaving the girl with O'Brien--truly "two of a kind," who'll be able to line up suckers elsewhere.
