Della meets up with an old friend, a child that she used to baby-sit and she and Perry are invited to meet the friend's new wife, Suzanne. Meanwhile, Suzanne rents out her house to four gentlemen who are having a meeting about a plan that could get them all rich - little realizing that Suzanne is taping the whole conversation.
