Would a loving God really give you the power to kill a man by turning him into dust? ...It's Boston, Massachusetts, in 1965, and Father Bill Sullivan is a Roman Catholic priest with a secret - he wields awesome energies he believes are given him by God. The "Power of the Holy Spirit" manifests around him as nebulous tentacles of purple and gold energy and smoke. The Power allows "Good Samaritan" - as he calls himself - to hover, grab criminals and restrain them, subject thugs to the experience of their own crimes in his "Confessional", and occasionally render ultimate judgment by turning perps into dust as he proclaims, "Remember Man that thou art DUST and unto dust thou shall return!"
A new menace is tangling with Good Samaritan, a creature preying on children. And "normal" life is presenting its own problems as the new Cardinal of the Archdiocese apparently has it in for Father Sullivan!
