In 1964, in the Bronx, New York, a priest named Brendan Flynnplayed bySeymourcame to St. Nicholas Catholic School. Most of the students came from a long- standing religious school. Mission school for Catholic families. For a long time, this school has been dutifully in charge of the nun Aloisius Bayville, who believes in the power of discipline and fear, and has formulated strict dogma to make it here Children who go to school can receive a good education and cultivate a pious attitude. But all this changed after Father Brendan Flynn arrived.
The serious and old-fashioned Sister Aloisius has always adhered to the dogma of rigorous scholarship, and every child must abide by discipline and be under strict supervision. Father Flynn advocates a relaxed atmosphere to educate children. His teaching style is lively and all the inherent rules and regulations seem to be incompatible with him, and Father Flynn often violates the majesty of Sister Aloisius.
Soon, due to the influence of political changes, the Saint Nicholas Catholic School accepted the first black student, Donald. Father Flynn seems to be very concerned about this little black boy, and the young nun Jamesinadvertently discovered some small signs that Father Flynn may have special feelings for Donald. When this pious and innocent nun told the principal Aloisius what she had seen and what she had in her heart, Sister Aloisius was extremely furious and began an investigation into the truth. In fact, Sister Alois did not find any evidence to prove the charges against Father Flynn, but she still believes that Flynn is guilty. Sister Aloisius and Father Flynn are involved in a battle without gunpowder.
