Monsignor is a 1982 American drama film directed by Frank Perry about a Roman Catholic priest's rise through the ranks of the Vatican, during and after World War II.

Along the way, he involves the Vatican in the black marketeering operations of a Mafia don, and has an affair with a woman in the postulant stage of becoming a nun.

The cast includes Christopher Reeve, Geneviève Bujold, Fernando Rey, Jason Miller, Joseph Cortese, Adolfo Celi, and Leonardo Cimino.

With the Vatican having financial difficulties during World War II, a young priest from America is sent for, recommended because of his accounting skill.

To raise money for the church, he is willing to enter into a black market operation with the Mafia, selling cartons of cigarettes by the tens of thousands for a percentage of the take.

The priest's morals are strained further when he develops a romantic interest in Clara, a young nun who is having a crisis of faith.
