Summary

On the last night of summer 1962 in a small California town, a group of recent high school graduates cruise the strip, chase girls, drag race, and confront their uncertain futures. Two friends are set to leave for college the next morning, while others wrestle with whether to stay behind in the only world they've ever known.
