As Carrie's birthday approaches, she finds herself at the center of a friend's domestic drama, while Samantha faces the truth, Miranda has an awakening, and Charlotte seeks solace in a new male.

In order to get over her divorce, Charlotte takes up tap-dancing, but it doesn't solve her emotional state. Richard has enough confidence to admit doing it with Bebe and invite Samantha to join him in the luxury shower in one breath; she obliges, but still is vexed enough to have a quickie just to spite Richard, who doesn't bother. Aidan joins his fiancée Carrie in their smaller shower. Miranda learns from her gynecologist the baby is a boy, and is terrified not to be flooded by maternal feelings. The two brides go wedding shopping together, but Carrie chokes in a dress, an extreme symptom of wedding gibbers, or is it more serious?
