England trembles in the grip of a devastating epidemic. But in a brutally remote coastal village, quiet Derek waits for love and life to really begin. Then Lydia arrives. She burns brightly – incandescently. Beyond Derek’s wildest dreams. And she is hiding something. When Derek discovers her secret – out by a restless sea, they are both propelled into a strange new world of conflicted desire and dangerous loyalties. Where terrifying forces test their courage and humanity.

Joining Alex are Alexander Arnold (best known for playing Rich Hardbeck in Skins and most recently playing Jim Carter in Poldark) and Hannah Britland (who played Lydia in Skins and most recently Sam in Fresh Meat). Over 14s only. Running time: 2 hours including interval. Contains smoking.
