In a suburban neighborhood, two eccentric teenage friends, Enid and Rebecca, navigate the summer after their high school graduation with a mixture of cynicism and disdain for the conventional world around them. With no clear plans for their future, the duo spends their days wandering aimlessly, critiquing pop culture and the people in their town. Their bond is strong, characterized by a shared sense of humor and disenchantment with the adult world they are about to enter. However, as the reality of adulthood looms closer, their friendship begins to show signs of strain. Enid’s interest in obscure art and Rebecca’s desire for a more traditional life start to pull them in different directions.

Their aimless wandering takes a turn when they encounter Seymour, a lonely, middle-aged man with an avid interest in vintage jazz and blues records. Initially, Enid plays a prank on Seymour that leads to an unexpected friendship, driving a deeper wedge between her and Rebecca. As Enid becomes more involved in Seymour's world, she finds a kindred spirit in his alienation and dissatisfaction with life. This new friendship challenges Enid to reflect on her own views of the world and her place in it. Meanwhile, Rebecca starts making steps toward the adult life she thinks she desires, further complicating her relationship with Enid. This period of transition tests their friendship and forces both to confront their future.
