Summoned to a convent, Dr. Martha Livingstone, a court-appointed psychiatrist, is charged with assessing the sanity of Agnes, a novice nun accused of murdering her newborn child. Further arousing Dr. Livingstone’s suspicion, Mother Superior Miriam Ruth tries to keep her young charge away from the doctor’s pointed questions. In trying to find out who killed the infant as well as attempting to identify the father of the tiny victim, Livingstone forces all three women to reexamine the meaning of faith, the power of love, and the authenticity of miracles.
