Summer Love is a sequel to 1957's Rock Pretty Baby, with John Saxon repeating his role as aspiring musician Jim Daley. When his band is hired to perform at a summer resort, Jim falls in love with two girls: sweet Joan Wright (Judy Meredith) and not-so-sweet Erica Landis (Jill St. John). Meanwhile, Jim's buddy Mike (John Wilder) woos the band's pert vocalist Alice (Molly Bee). Also returning from Rock Pretty Baby are Edward C. Platt and Fay Wray as Jim's bewildered parents, Shelley Fabares as the appropriately yclept Twinkie Daley, and the inimitable Rod McKuen as funky band member Ox Bentley. Oh, and Troy Donahue also shows up, just in case there was any doubt as to when this film was made.
