It's summer in the Hamptons, and cougars are on the prowl. Nate is in the midst of a steamy affair with Catherine Mason, a married woman, and Serena and Nate fake a relationship to cover for his tryst. Serena is mourning her relationship with Dan, who has spent the summer assisting a big-name author and playing the field. Blair shows up with a new, mysterious boyfriend, which makes Chuck jealous, and Jenny gets exploited as an intern for Eleanor Waldorf's design company. Jealousies, lust, and resentments flare at the exclusive White Party—attended by all our favorite Upper East Siders.
