Father Ray, a card-playing, cocktail-sipping, blues-loving priest, ministers to his parishioners at St. Thomas, a large urban church in an inner-city neighborhood. He grapples with his own personal failings, including occasional crises of faith. Offering support are wise older priest Father Leo, young idealist Father Eric, and feminist nun Sister Maureen. (The series was co-created by a Jesuit priest named Bill Cain and producer David Manson.)
