Tired of the crime overrunning the streets of Boston, Irish Catholic twin brothers Conner and Murphy are inspired by their faith to cleanse their hometown of evil with their own brand of zealous vigilante justice. As they hunt down and kill one notorious gangster after another, they become controversial folk heroes in the community. But Paul Smecker, an eccentric FBI agent, is fast closing in on their blood-soaked trail.
The Boondock Saints II: All Saints Day is a 2009 vigilante action thriller film written and directed by Troy Duffy, based on a story he co-wrote with his brother Taylor. A sequel to The Boondock Saints (1999), the film stars Sean Patrick Flanery, Norman Reedus, Clifton Collins Jr., Julie Benz, Peter Fonda, and Billy Connolly. Set eight years after the events of the first film, it follows Irish fraternal twin brothers Connor and Murphy MacManus living a quiet life in Ireland with their father Noah, formerly known as "Il Duce" (Connolly).
