This is the film version of William Inge's Pulitzer Prize winning play about an Oklahoma family. Rubin (Robert Preston) and his wife Cora (Dorothy McGuire) have marital problems, which drives Rubin into the arms of Mavis (Angela Lansbury). Reenie (Shirley Knight) is in love with a Jewish boy Sammy (Lee Kinsolving). Sonny (Robert Eyer) rounds out the family of four, a boy who is afraid of The Dark At The Top Of The Stairs. All in the family are metaphorically afraid of something as they sort out their confused lives. Knight was nominated for an Academy Award for her performance in the film.
