No one could ever have predicted that Tom O’Meara (Harrison Ford) and Frankie McGuire aka Rory Devaney (Brad Pitt) would come to know one another. The New York City cop and the Irish terrorist have nothing but their heritage in common. But when Devaney arrives in the US on a terrorist mission, he takes on the perfect false identity, hiding in plain sight as an innocent young man seeking refuge from his country’s troubles. O’Meara, a man with a large heart, agrees to open his family home to this supposed stranger in need, without knowing anything about his past.

Two countries, two men, two opposite ways of trying to do the right thing. Yet their fates will be fused together when their very different methods of seeking peace and justice wind up on a violent collision course with one another.
