Four male students are graduating high school and constitute the school’s entire graduating class. It’s a very tiny town. They’re doing the equivalent of a graduation party: parked smack dab in the middle of the highway (which is utterly unoccupied) in lawn chairs, drinking beers and talking.
I think one of them decides to stay instead of leave town to go to college.
Ring a bell?
I can’t recall if I thought it was any good, though.
