Prologue: August 15, 1983 London

Father John Palmer is groomed to be America's first Pope and the first African-American to reach such a high office in the Catholic hierarchy. Sister Paula Villa - the accidental star - captured the world and amassed a huge fan-base through her cable TV program. Brother Pedro Gonzaga slowly builds himself as a formidable figure in the Vatican Bank. Sister Lily White is the epitome of what pastoral work ought to be. These unlikely people found themselves playing roles nobody wanted. They are The Four.
