After three weeks of calls from Richard, Samantha is out for revenge, and in public. Fortunately it's fleet week, when the city swarms with USNavy boys, who invite the non-moms to a hot party.

Samantha's announcement she's giving Richard another chance after his unfaithfulness, as nobody's perfect and it was 'only sex', is such a bomb-shell that even Charlotte makes an obscene gesture. Although Miranda is atheist, she can't deny Steve's entire Catholic family having the baby baptized.

Miranda and Carrie, who came to get her, miss his private jet because Steve is really afraid to take care of Brady for more then two hours, till Magda offers to help. Once there, Charlotte lives it up and Miranda switches between gambling and getting ready for bed, but Samantha can't handle the fact Richard seems to know all female staff intimately.

When Carrie is shown the all too naked cover her publishers planned for her columns book, she's shocked, it just screams hooker, so she turns to Samantha who accepts to do her PR for peanuts. Charlotte swallows her pride to seek hope in another advice book.

Samantha turns up as Carrie insisted, but refuses to put her hat and veil on again, so she literally scares off Harold Keenan, The New Yorkers critic. Stanford is proud to present his stunningly gorgeous boyfriend Marcus, date-less Anthony is green with envy.

Charlotte and her lawyer who dropped off the last divorce papers at her hard-kept place, which she now considers selling, end up having sex in his apartment. In Frisco, Carrie is mortified to be the opening act for a canine TV puppet, but finally finds a sex partner: Mr. Big, who came to hear about his 'character' in her book.
