Newly hired at a private school, teacher Laura Siddons (Wendy Hiller) suspects that one of her students, a girl named Gloria (Gigi Perreau), is having a clandestine romance. Laura and her gentleman friend, Ben (Robert H. Harris), eventually catch up with Gloria and confirm their suspicions: the girl is not only in love, but also married! Gloria begs Laura not to tell Gloria's mother for fear that the old woman will have a heart attack, whereupon Laura promises to keep the girl's secret -- but things take a sinister turn from this point forward. ~ Hal Erickson, Rovi
