College-bound Gidget (Cindy Carol) is vacationing in Rome for the summer with faithful boyfriend Jeff, aka Moondoggie (James Darren) and their friends. Chaperoning the pair is Aunt Albertina (Jessie Royce Landis). However, Gidget's father Russell, worried about his daughter being abroad, asks an old friend of his, named Paolo Cellini, to keep an eye on Gidget to see that she stays out of trouble. Complications set in when Gidget begins to fall for the much older Paolo.[3]
The film was shot on location in Rome, Italy, with some scenes filmed on Italian beaches. In a parody of La Dolce Vita, Gidget attends a high society party and goes into the Trevi Fountain.
With Deborah Walley pregnant at the time of filming, Cindy Carol, who had previously acted under the name Carol Sydes took over the Gidget role[4] and was signed to a Columbia Pictures contract.
When Gidget, played with the proper pout and correct ingenuousness by Cindy Caroll [sic], arrives in Rome with her group of happy friends, she is bound to fall in love with a married and handsome Italian magazine writer, enjoy such exotic delicacies as fettucini and chicken cacciatore, and experience the thrill of attending a 'Dolce Vita' cocktail party. As one of Gidget's friends explains, it's part of her 'growing up.' Gidget falls out of love in time...and all ends happily. Jeff sums up the entire experience in two immortal sentences: 'I guess everybody falls in love in Rome in the summer time. It's that old devil Italian moon.'"[5]
