Hoping to leave his dark past behind him, former assassin Finbar Murphy (Liam Neeson) leads a quiet life in a coastal Irish town, far from the political violence that grips the rest of the country.

When menacing terrorists show up, Finbar soon discovers that one of them has been abusing a local girl. Drawn into an increasingly vicious game of cat and mouse, he must choose between exposing his secret identity and defending his friends and neighbors.
