Some friends introduce her to Sean, ‘The Marrying Guy’; when she can’t keep up on his quick-march to commitment, he ditches her for commitment-phile Charlotte. Miranda’s colleague from work, Jeff, introduces her to a lesbian, Sid, at a baseball game, and they are invited to her senior partner’s dinner party.
