At the time, Margie was living with her grandmother (Esther Dale) right next door to her friend Marybelle (Barbara Lawrence). One day, just as Margie is about to get a ride home with Marybelle and her boyfriend, the elastic on her bloomers breaks and, not wanting Marybelle’s boyfriend to find out, Margie ducks into the school library to fix it. While hiding in the stacks, she meets none other than Mr. Fontayne.
But despite their awkward first encounter, Mr. Fontayne is quite fond of Margie and goes out of his way to compliment her when she does well on assignments, which makes her the envy of the other girls in school. One night, Margie goes ice skating with some of her classmates and unfortunately, that elastic in her bloomers breaks again. She falls and sprains her ankle trying to fix it and everyone, including Mr. Fontayne, rushes to see if she’s okay. Mr. Fontayne sees her fallen bloomers and discreetly takes them so nobody else will see. Later that night, he visits Margie at home and to return her bloomers.
Just before the prom, Margie’s boyfriend Roy (Alan Young) gets sick and can’t bring her. Margie’s grandmother helps by arranging for Margie’s father to take her to the dance and she tells Margie she will have a surprise escort. So when Mr. Fontayne stops by her house just before the dance, Margie is thrilled. However, he’s only there to drop off a grade. He’s taking the school librarian to the dance instead, but he says he’d like to take Margie to the next dance. Although Margie is disappointed, she’s happy to see her father.
Margie has a wonderful time at the prom and lots of guys, including Mr. Fontayne, are eager to dance with her. But once again, Margie has problems with her bloomers. This time, she tries to hide it by pretending to faint and, of course, Mr. Fontayne comes to help again. Cutting back to modern day, Margie and Joyce are in the attic having a good laugh at the story and it turns out Margie went on to marry Mr. Fontayne.
If they tried to remake Margie today, no doubt it would feature a special cameo appearance by Chris Hansen from To Catch a Predator, emerging from behind a corner to ask Mr. Fontayne to have a seat. I really wish I could have been able to see Margie for the sweet, harmless, wholesome movie it was intended to be, but I can’t.
