It's the summer of 1965, and the members of the graduating class of upscale Westwood High are eager to reinvent themselves. Valedictorian Mary Beth (Lucy Deakins) wants to attend a liberal university. Surfer bum Stick (Rick Schroder) plans to enlist to fight in Vietnam. Calvin (Kenny Ransom) lives in the poor Watts section of Los Angeles, which is slowly erupting in violence. As the summer nights grow long, they'll all be forced to make decisions that will affect the rest of their lives.
