After two years of college abroad, Gidget returns to Santa Monica. She discovers that the letters she wrote to her boyfriend Jeff, intended to make him jealous, have backfired, and her attempts to patch things up with him are rebuffed. Inspired by a speech she hears on television made by the United States Ambassador to the United Nations, she hops a bus to New York City to work for the United Nations.
She meets the ambassador, who finds her a job, but because she has only two years of college education, the best position the United Nations will offer her is tour guide. She meets and has a fling with Alex Mac Laughlin, an Australianagronomist who finds her and two of her fellow employees an inexpensive Greenwich Village apartment, managed by the eccentric Louis B. Latimer, a grown child actor has-been attempting a comeback as an independent film director.
Gidget has a number of comical and romantic adventures before being reunited with former boyfriend Jeff.
