Germaine Morris, considered an ugly duckling, is in love with her employer, Gerald Gray, an interior decorator who caters to the smart set, and is concerned over his affair with Claire Fenton, the wife of a wealthy broker.

When Claire invites Gerald on a yachting trip to Florida, his friend Bunny West invites showgirl Chouchou Rouselle to pose as Gerald's fiancée, but Germaine determines to substitute her own womanly beauty.  In Florida she wins the attentions of all the men, causing a quarrel between Claire and Gerald; and Fenton hopes to obtain a correspondent as grounds for divorce.

When Germaine, in her negligee, delivers a pipe to Gerald's room, he proposes.  Fenton suggests that he take Germaine, leaving Claire and Gerald to go their way; however, Smith, the showgirl's admirer, tries to claim her and is beaten by Gerald, who effects a reconciliation between the Fentons and claims the girl he loves.
