Everyone knows who won. But not everyone knows how. That’s the premise behind HBO’s new film, Brexit, starring Benedict Cumberbatch. The provocative feature-length drama goes behind the scenes of the Brexit referendum in the summer of 2016, revealing the personalities, strategies and feuds of the “Leave” and “Remain” campaigns.

Cumberbatch plays Dominic Cummings, who spearheaded the “Vote Leave” campaign. The film also features Rory Kinnear as Craig Oliver, Prime Minister David Cameron’s director of communications and head of the “Remain” campaign.

Brexit premieres Jan. 19 at 9 p.m. on HBO. Watch the trailer below:
