Caitlin is 17 and “all legs,” like a Barbie. At school, boys drool over her, girls say she should send photos to fashion magazines, and teachers become frustrated at her lack of effort. Caitlin doesn’t study for tests or turn in essays on time. She thinks school is separate from life.

Over spring break, Caitlin and her mom travel to the Italian Alps, where she has sex for the first time, with a ski instructor. She doesn’t love him, but she uses a condom, and she’s glad she got it over with. She thinks sex and love don’t go together.

On the island, the two teens drive around in Caitlin’s red truck and play Frisbee on the beach. Bru tackles Vix and asks her about the “mask” he claims she wears. He calls her Double and Caitlin Trouble. Unlike Caitlin, Vix doesn’t “advertise.” Bru touches Vix’s shoulder, and her skin gets hot. Later that night, he kisses her goodnight, and her crotch gets “damp.” Bru asks Vix if she’s scared of him, and Vix asks Bru if he’s scared of her. Bru answers yes.
