Amy Madigan heads the cast as Mary Larkin, the no-nonsense madam who runs Diamond Ranch -- a cathouse on the outskirts of Reno, Nev., that caters to the carnal needs of any client who can pay the going rate. As the bordello's sexy ladies ply their trade, Mary keeps a watchful eye on her charges, including a struggling single mother (Jessica Collins) and an ex-actress whose Hollywood dreams evaporated (Nicki Micheaux).
