Diary of a Lost Girl

When her husband Fred goes bankrupt, Lily Morton is forced to give up the trappings of wealth and move into a humble home while Fred attempts to fight his way back to prosperity. Resentful of her modest circumstances, Lily accepts her friend Marion Garland's offer to introduce her to Mrs. Farington, a woman who will pay handsomely for Lily's escort services. Lily goes to work for Mrs. Farington while her unsuspecting husband struggles to regain his former wealth. While managing an apartment house for one of his wealthy clients, Fred visits Mrs. Farington, a tenant, and, noticing a framed picture of Lily, asks to be introduced to the girl. Mrs. Farington arranges the rendezvous, and when Lily arrives, she is confronted by her enraged husband who chokes her to death. At this moment, Lily awakens from her nightmare, and chastened for her superficiality, begs Fred for forgiveness.

A young couple has a final argument. One wraps the other in a shower curtain and attempts to carry her away, but she has strength enough for one last strike.

Artist Mary McLeod, while returning to New York, discovers she has lost her train ticket; young Phillip Dominick, a millionaire playboy, offers her his drawing room, posing as her brother, and their friendship in time develops into love. They are married, and Phillip takes his bride to his wealthy mother, on whom he is financially dependent. Mrs. Dominick, however, has plans to separate the couple and marry Phillip to a society girl, and though Mary begs him to take her away, she agrees to remain until the birth of her baby. The grandmother assumes full charge of the child, but despite careful nursing the child dies, and a subsequent misunderstanding causes Mary to leave. Phillip finds her and promises to start a new life in their own home on his own resources.
