Set in a cramped St. Louis apartment in the mid-1930s, where Dorothea, a high school civics teacher, rooms with Bodey, a plain but caring and kind-hearted German-American spinster. Dorothea, a hopeless romantic, dreams of marriage with the principal of the school, while her protective roommate, Bodey, hopes to match Dorothea up with her fat, cigar-smoking twin brother, Buddy. Bodey tries to persuade Dorothea to join them for a picnic at Creve Coeur, a nearby amusement park. Their departure is delayed by the arrival of Helena, a snobbish, tart-tongued art teacher, who wants Dorothea to share an apartment with her in a better part of town. Inevitably, a struggle evolves between Bodey and Helena, with Dorothea, lost in her dream world, caught between these two strong women.
