Amid daily reports of violence, Cushla lives a quiet life with her mother in a small town near Belfast. By day she teaches at a parochial school; at night she fills in at her family's pub. There she meets Michael Agnew, a barrister who's made a name for himself defending IRA members. Against her better judgment - Michael is not only Protestant but older, and married - Cushla lets herself get drawn in by him and his sophisticated world, and an affair ignites. Then the father of a student is savagely beaten, setting in motion a chain reaction that will threaten everything, and everyone, Cushla most wants to protect.
