Designated the King's 'Angel' because of his good looks, he finds himself falling in love with the young woman who is the companion of the King's adulterous and estranged wife, Kirsten. With his loyalties fatally divided between duty and passion, how can Peter Claire find the path that will realize his hopes and save his soul?
