Lucille Vale is in love with struggling architect Paul Arden, but her mother believes that Allen Granat is a more suitable match. Lucille's mother prevails, and Lucille leaves Paul a note in their secret hiding place saying that she is going to marry Allen. Paul is injured when thrown from a horse and does not receive the note. He is nursed back to health in the home of entomologist Thomas Wiggan, whose son Johnnie is in love with Marion Vale, Lucille's younger sister. Two years later, Lucille and Allen return to the estate, very much in love, and engage Paul's services. The note is found, still waiting in the secret hiding place. After many complications, and with the help of her friend Suzanne Russell, Lucille recovers the possibly incriminating note.
