Gidget (Sally Field) despairs when she's unable to line up a date for her class luau. Her brother-in-law John (Peter Deuel) offers to escort her, not so much out of gallantry as to gather research for a psychology paper on typical teenage behavior. Unfortunately, John's wife (and Gidge's sister) Anne (Betty Conner) is unaware of her husband's motives--and for the second time in as many weeks, she jumps to the wrong conclusion. Keep an eye out for Beverly Adams, a sexy starlet best known for her appearances as Lovey Kravezit (sic!) in Dean Martin's "Matt Helm" films. ~ Hal Erickson, Rovi
