Jane and his team are called in to investigate the murder of James Meier, the operations manager for a resort casino, whose right hand has been found straddling the borderline between California and Nevada.
Was this a mob hit or someone trying to send a message? A love triangle gone wrong? Or something else entirely?
While Lisbon and the rest of the team look into Meier's business dealings, Jane uses his mentalist skills at the card tables to rake in chips, which he uses to but the team some outrageous presents, while at the same time, studying the players on the floor.
In the end, Jane discovers Meier's son-in-law's secret life as a degenerate gambler and plays on his gambling obsession to ultimately lure out the truth.
