Teenage friends Carson and Becca are enjoying a night out in Rockaway and Coney Island when they’re joined by a new friend, Julie.

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.
