The British government cabinet minister Henry Danby is murdered by an IRA gunman, Billy Downes, in front of his wife and children outside his home in London. Downes then escapes to Belfast and army officer Harry Brown is sent undercover into Belfast's Catholic community to track down the assassin. Brown is chosen for the mission because he is an Ulsterman who has previously done similar work in Oman.
