Fictionalized account of the events which lead to the 1996 murder of journalist Veronica Guerin. Sinead Hamilton (Joan Allen) is a reporter employed by the Irish Sunday Globe. In the course of her work she becomes interested in the possibility of exposing the corruption which allows Dublin's drug lords to lead the lives of respectable businessmen, and of working towards a reform of Ireland's notoriously ineffective criminal laws. But her investigations earn her some enemies in high places, and Sinead soon receives threats to her own well-being.
