Ivy (Zoe Kazan) is a college student suffering from juvenile myoclonic epilepsy who just returned home to Brooklyn on summer break. While she stays at her mother's, her childhood friend Al (Mark Rendall), who's also home from college, asks to crash on their couch because his parents rented his room. Over the course of the break, Ivy and Al will spend most of their time together, strengthening their already deep bond, especially after Ivy's distant boyfriend Greg dumps her via a phone call.
