In New York, Mae Swasey (Thelma Ritter) practices the delicate art of matchmaking. When a handsome optician, Matt Hornbeck (Scott Brady), stands up his original match at the altar, Mae quickly sees an opportunity to put him with the more suitable Kitty Bennett (Jeanne Crain), a model and shop owner. Although Matt is reluctant to be tied down, he falls in love with Kitty and all goes well -- until the couple, neither of whom have known what Mae does, suddenly finds out about her profession.
