AIn the opening of the film, the brothers are in church praying when the priest begins talking about a victim named Kitty Genovese who was killed a long time ago in the middle of day and everyone watched but did not respond and about the indifference of good men towards evil. After hearing this, Connor states, "I do believe the monseigneur's finally got the point", to which Murphy responds, "Aye." Later on, its Saint Patrick's day and the brothers are at a bar drinking when three Russian gangsters come in and state that they will close the bar, but the brothers don't allow them, to which a fight begins between them, to which the Russians are left badly wounded. As the brothers rest in their apartment, the Russians come back and threaten the brothers. Connor is handcuffed to a toilet while Murphy is taken outside to be shot in the head. Connor, out of rage, breaks the toilet apart and throws it down the complex and hits the Russian, killing him. Connor jumps on the other Russian, to which Murphy finishes him off. The brothers go to the police station to prove that it was self-defense. Meanwhile, the police let them stay in a holding cell to avoid the media. While sleeping, water falls from the crack of the ceiling onto their bodies, symbolizing baptism and forgiven sin. The brothers realize this and say to each other, "Destroy that which is evil so that which is good may flourish." The brothers take the money and jewelry they took from the Russians they encountered and buy guns. Seeing all the sin that has went on, violence, drug use, rape, thievery, they swear that they will execute all evil men who have done sin in order that peace and goodness can be restored and evil can be stopped.
AIl Duce was hired to kill the vigilantes, however, he didn't realize that they were his children, nor did Connor and Murphy realize that Il Duce was their father. It wasn't until Il Duce was about to ambush them at the end, when he overheard them saying their family prayer, that he obviously realized would be too much of a coincidence for someone else to know. Also, he knew he fathered twin sons; they just haven't seen each other for about 25 years.
