In 2006, Northern Ireland's bloody troubles had dragged on for decades. Now with the growing threat of a new generation inspired by the 9/11 attacks that could escalate the conflict to new levels of destruction, both the Catholic Republican and the Protestant Unionist sides are finally persuaded to seriously explore a peace agreement at UK Prime Minister Tony Blair's urging. Unfortunately, the principle negotiators, firebrand Democratic Unionist Party leader Ian Paisley and Sinn Fein politician Martin McGuinness, are decades-long implacable enemies. With the Prime Minister and his MI-5 staff nervously watching from secret cameras, the two foes undertake a journey together in which they bridge the seemingly unbridgeable and change the course of history. Starring Timothy Spall & Colm Meaney.
