Continuity mistake: To prevent two welfare workers from taking the child of her unemployed roommate, Betty Lou Spence claims the baby is her own. A newspaper article, shown in close-up, says she fought "all who sought possession of the tiny child." The word "possession" is hyphenated. One line of the article ends with "pos-" and the next line begins with "session." When the newspaper is shown again, the hyphenation is different. One line now ends with "posses-" and the next line begins with "sion."
