The Boondock Saints II: All Saints Day is a 2009 American vigilante film written and directed by Troy Duffy. The film serves as a sequel to the 1999 film The Boondock Saints. The film stars Sean Patrick Flanery and Norman Reedus, who return to their roles, as well as several of the other actors from the first film.
The film takes place eight years after the events of the original Boondock Saints, as fraternal twin sibling vigilantes Connor (Flanery) and Murphy (Reedus) are living a quiet life with their father, the former assassin known as "Il Duce". However, they are drawn back into action after someone attempts to frame the brothers for the murder of a priest in Boston. The duo travel back to the United States, where they meet some old friends and are pursued by Eunice Bloom (Julie Benz), an FBI agent and former protégé of Agent Smecker.
After the McManus brothers, Connor and Murphy (Sean Patrick Flanery and Norman Reedus), and their father, Noah (a.k.a. "Il Duce") (Billy Connolly), assassinated Joe Yakavetta, they fled to Ireland. Eight years later, their uncle Sibeal (Mairtin O'Carrigan), a priest, arrives to inform them that a renowned Boston priest was murdered by a mysterious assassin who attempted to frame the Saints by using their ritual assassination style. In response, the brothers dig up their old gear and weapons and depart for the United States.
