As Bluebell is hit by an intense heat wave, Zoe (Rachel Bilson) discovers that the hot weather makes everyone act differently and with a lot less inhibition. In fact, it takes all of Zoe's strength to ignore her heat-induced attraction to Wade (Wilson Bethel) until it gets the best of her. Meanwhile, Lemon (Jaime King) prepares for the arrival of George's (Scott Porter) family, determined to win them over, but her emotions get the best of her when Lavon (Cress Williams) shows up to the same restaurant with his date, Didi (Nadine Velazquez).
