Innocent Mildred Harker is framed by her husband, Walter, in a divorce suit and loses custody of her child.  Disillusioned and heartbroken, she takes up residence in a cheap hotel and becomes a showgirl at the New York Winter Palace Roof, where she meets a group of gold-digging "lilies."  Ted Willing, a wealthy man-about-town, becomes her devoted admirer, but she is suspicious of accepting his financial help even when he mentions the whereabouts of her daughter.

Later, she discovers that the child has forgotten her, and she accedes to Willing's proposal.  During a party, she learns of her child's death, and, grief-stricken, she rushes into the streets; she is fined for disorderly conduct, but Willing comes to the police station and she finds comfort in his arms.
