Mid-1990's. In Ireland, there is a real war between Catholics and Protestants. The situation is complicated by conflicts of local drug lords. People learn the terrible truth about the crimes not from the police and government officials, but from a fearless journalist os an independent publication Veronica Guerin. Risking her career, life and family, she finds the most reliable facts. However, her articles are not to the liking of the underground drug dealers, and they begin a real hunt on her. But with each new attempt, Veronica is becoming increasingly popular. In 1996, she still dies from the hands of assassins, which entails a wave of protests and a complete revision of many laws in Ireland, as well as the arrest of the main authorities of drug traffickers.
