"Everyone knows who won. But not everyone knows how." The result of the Brexit referendum in the summer of 2016 caused a political earthquake that laid waste to the normally stable British establishment and sent political tremors across the world. This punchy and provocative feature length drama goes exclusively behind the scenes of the "Vote Leave" campaign, unpacking the personalities, strategies, and feuds of the winning side, and exploring the new world of data driven campaign tactics. Stars Benedict Cumberbatch and Rory Kinnear.
