All they want is to say I do. But just to prove who's in charge, Cupid throws two lovebirds nothing but screwballs on their way to the altar. A few months after her wedding to John Agar, 18-year-old Shirley Temple stars as an on-screen bride in this breezy comedy set in Mexico City. Temple plays Barbara, whose prospective husband (Guy Madison), a GI, has a two-day pass to marry her. At least three days` worth of complications ensue: a delayed flight, booked-up hotels, a jitterbug with the wrong partner, a right hook to the wrong chin, a fateful dip in a swimming pool. . .and a gallant (and older) American vice-consul who makes Barbara's heart beat a little too fast. Is she marrying the wrong guy? Expert farceur Franchot Tone plays the sophisticated vice-consul, who has his own fiancee to worry about. William Keighley, who proved his comedy mettle with The Man Who Came to Dinner and George Washington Slept Here, guides the fun.
