Dangerous Business (1920)

Nancy Flavell, the spoiled daughter of a rich father, makes a career of capriciously falling in and out of love while disregarding the sincere love of Clarence Brooks, her father's secretary. War breaks out and Clarence enlists and is sent overseas. When Mrs. Flavell announces that she has picked out a rich husband for Nancy, she escapes matrimony by declaring that she is already married to Clarence. Returning home as a war hero, Clarence discovers Nancy's deception and carries her off to his mother's house, where he forces her to spend the night in an adjoining bedroom. Nancy, believing that her reputation has been tarnished by the incident, insists upon a quiet marriage to be followed by a quick divorce. Clarence refuses her terms, and when Nancy finally agrees to cement her commitment to him with a baby, the two are married.
