Bette Davis is "That Certain Woman" in this 1937 remake of "The Trespasser." Davis is the widow of a mobster killed in the Saint Valentine's Day massacre. Now she works for a businessman Lloyd Rogers (Ian Hunter) and uses the name Mary Donnell. She has two men in love with her: her boss Lloyd and a man from a wealthy family, Jack Merrick (Henry Fonda). Knowing who she is thanks to a news story, Merrick's dad (Donald Crisp) is violently opposed to the marriage, but she and Jack marry. They break up right after the honeymoon, thanks to the dad, but during the honeymoon, Mary conceived Jack Jr. Jack goes off to Paris and marries Flip (Anita Louise), not knowing anything about the baby. Meanwhile, the unhappily married Lloyd is hanging around Mary.
