State of Grace

Terry Noonan (Penn) returns to his old neighborhood with a score to settle. He's now an undercover cop dead-set on taking down an Irish mob family headed by Frankie Flannery (Harris) and his hot-headed brother Jackie (Oldman). But when Noonan infiltrates the family, his old feelings for the Flannerys sister (Wright) further heighten the stakes as he enters a violent showdown with them during a crowded St. Patrick's Day Parade!
