Archangel Gabriel and his three mischievous Prayer Ambassadors--Shirley, Goodness and Mercy--lend their celestial aid to three needy Christmas cases. Harry Alderwood, 86, prays that his increasingly forgetful wife, Rosalie, will agree to move into assisted living before he dies. Meanwhile, nine-year-old Carter Jackson begs God for a dog, even though his mother and father tell him that they can't afford to keep a pet, while Beth Fischer's mother prays that her divorced paralegal daughter, nightly engrossed in a World of Warcraft online game, will start a new life.
