Also starring James Franco and Emma Roberts, Palo Alto is about a shy, sensitive girl named April (Roberts), who is the class virgin, torn between an illicit flirtation with her soccer coach Mr. B (Franco) and an unrequited crush on sweet stoner Teddy.

Emily (Levin), meanwhile, offers sexual favors to every boy to cross her path – including both Teddy and his best friend Fred (Nat Woolf), a live wire without filters or boundaries. As one high school party bleeds into the next – and April and Teddy struggle to admit their mutual affection – Fred’s escalating recklessness starts to spiral into chaos.
