Teenage friends Carson and Becca are enjoying a night out in Rockaway and Coney Island when they’re joined by a new friend, Julie. The vibe is loose and fun, except that Carson feels a little left out and threatened by Becca’s rapport with Julie, who has the devil-may-care confidence of the archetypal “cool girl.”
When Julie incites their trio to break into a nearby closed-off pool at night, they encounter trouble, and Carson makes a key decision — and tells a lie — that has dark consequences.
