BOSTON POLICE OFFICER Willie Dwyer is haunted by a decade-old secret, a secret he carried to America. Swept up in the tumult of post-war 1919, Irish-American immigrants, the backbone of Boston's police force work grueling 60-100 hour weeks for about $2.00 a day. In Ireland, the Republican Brotherhood wages a guerrilla war with England for national sovereignty, supported by Boston's Irish neighborhoods. Frustrated by political promises, Boston's guardians strike for fair pay and better working conditions. And as the city erupts, Willie Dwyer's nemesis crosses an ocean and comes to hunt him down.
