In the aftermath of the 2017 General Election, Stacey Dooley heads to Northern Ireland to find out exactly who supporters of the DUP are. She meets people who voted for a party that is both anti-Gay marriage and anti-abortion even when some don't agree, and discovers that the place is still bitterly divided years after the troubles. Her investigation plunges her into the bitter politics of Northern Ireland where British and Irish identities coexist with unease.
