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.
