At school, Molly finds a discarded CD with an eclectic mix of love songs on it, and she sets out to find the person who recorded it. Mary, meanwhile, is angry with Jerry but won't tell him why; and Harriet meets a mime and develops an interest in the art.

Jerry sets Molly up with a high-school senior who works in his office and has nearly the same personality traits as her dad, but the teen has her heart set on a new student from England. Meanwhile, Harriet asks Grant to teach her to play the guitar; and Rick has money problems with a bookie.

Jerry agrees to house an exchange student from Brazil after learning that the girl plays on her country's Olympic soccer team. Meanwhile, Molly is upset that she can't go to a party with Nick because it's scheduled for the same night as a piano recital by the twins.
