When spray-painted graffiti appears on the wall of Christy Burke's pub indicating that there's a killer on the premises, his grandson, Father Brennan Burke, is asked to investigate the vandalism. Though not at all keen on probing into the lives of the bar's clientele, he has little choice once a body is found on the property. Issuing orders from a cell in Mountjoy Prison, the pub's current owner wants the problem solved without the police anywhere near his building. Assisted by his pal Monty Collins and fellow priest Michael O'Flaherty, Brennan begins to uncover dark secrets worth killing for in the lives of the pub regulars. In addition to the events surrounding the pub, Brennan's murder investigation becomes overshadowed by ominous events in Belfast that may soon come home to roost in Dublin. Sinister figures are spotted in and around the pub, people are being followed in the street, and Brennan comes to possess explosive information that he cannot reveal to security forces. The situation compels him to take a hard look at Irish history and his family's place in it, and he can't shake the feeling that an act of violence in Northern Ireland is about to be avenged soon - and very close to home.
