Corinne d'Alys (Daniels) achieves sudden success on the stage and among her many admirers is noted artist Robert Townsend (Menjou). Robert is married to Elsa (Williams), the sister of John Elliott (Stone), the producer responsible for Corinne's rise to fame. The young woman's head is turned by the praise she receives and, despite John's warning against Robert, she permits the latter to paint her portrait and pay her a good deal of attention. John himself loves Corinne and believes that wisdom will come to her with time.
