Dr. Alec Stratton, a cold disciplinarian, can't believe one of his nurses is bringing her Druid medicines into his hospital. Vivie Field, Druid daughter of Lord Lance and Morgan Dellafield, shortened her name to avoid favoritism. She's the granddaughter of the ducal couple supporting Dr. Stratton's children's wing.

Alec refuses to believe in her Druid powers but can't overcome his desire for her Celtic beauty. When the sexual attraction between them grows, he warns her off. He confesses he wants a rich society wife to help him establish a wealthy practice. But when Alec discovers he's rejected a rich and aristocratic Vivie he reacts with horror, blaming her for not confiding the truth.

Vivie opens a clinic offering both Druid and conventional medicine, with her talents devoted to her patients. Another doctor assists her there and falls in love with her. Then Vivie's life is threatened.
