Over the summer of 1942 on Nantucket Island, three friends -- Hermie, Oscy and Benjie -- are more concerned with getting laid than anything else. Hermie falls in love with the married Dorothy, whose husband is an army pilot recently sent to the battlefront of World War II.

During the last years of World War II, Hermie, Oscy, and Benjie are coming of age. They went their separate ways when they graduated from high school in 1944. Benjie joins the Marines as Hermie and Oscy enter college. There, Hermie falls head over heels for another freshman named Julie, and the two old friends deal with a troublesome fraternity president who is in charge of hazings.
