In American graffiti, two teenage boys, scheduled to leave for college in the morning, spend a final summer night in 1962 cruising the strip. This leads to a series of misadventures for them and two other California teenagers. More American graffiti shows episodes in the same characters' lives as the 1960s continue and John Milner is drag racing, the Toad is in Vietnam, Debbie is a San Francisco hippie, and Steve and Laurie weather a domestic crisis.
