A Cabinet minister is gunned down outside his home in London by a member of the Provisional IRA. Security protocols come into immediate effect but the assassin evades them and manages to get back to Belfast unscathed. The military send Captain Harry Brown - a soldier who specialises in deep cover work in hostile situations - into the Falls Road area of Belfast a place notorious for civil unrest. His mission: to infiltrate himself into the local population hunt down the assassin and kill him on his own territory - proving to the IRA that they are not safe even in their own back yard. It is a terrifying game of cat and mouse taking place in a civilian-occupied war zone where one mistake means certain death.
