After a snap general election is called, Christopher, a campaign organiser for the Liberal Party, is sent to a Scottish island to campaign in a previously safe seat. He discovers upon arrival that one of the island?s former MPs has been living out of sight for a rather long time, haunted by personal tragedy and determined to make good on a promise to open a door to another world. Christopher finds himself asking what the truly Liberal course of action is and what sacrifices he is willing to make for it.
