Lt. Disher (Jason Gray-Stanford) is convinced that his widowed mother Maria (Susan Kellerman) is about to marry a con artist: namely, a much-younger antique dealer named Dalton Padron (Nestor Carbonel). As a favor to Disher, Monk (Tony Shalhoub) and Sharona (Bitty Schram) pose as a married couple and join a therapy group whose members also include the redoubtable Padron and his bride-to-be Maria. What neither Disher nor Monk know (but the audience does!) is that Padron is not only a crook but a murderer, who has already killed his partner to get his mitts on a fortune in hidden gold--and isn't about to stop at only one victim! ~ Hal Erickson, Rovi
