Veronica Guerin was a relentless crime reporter for The Sunday Independent during the early '90s. Guerin's violent murder in 1996 led to a revision of Ireland's laws and the creation of the Criminal Assets Bureau. Picks up with her pursuit of the underground drug trade in Dublin, which she suspects is led by mobster Martin "The General" Cahill. When Cahill's gang is attacked, she suspects mobster Gerry "The Monk" Hutch is responsible. Not deterred by threats or gunshot wounds, she uses thug John Traynor as an informer to help out her investigation of psychotic mobster John Gilligan.
