Lighthouse keepers Howell and Griffith are posted to 6 weeks on the Smalls - a desolate rock 20 miles off the Pembrokeshire coast. But the two men share a past, and because of what happens next, lighthouses would never again have only a crew of two. Based on a true story. Written by Alan Harris, and starring Paul Rhys as Howell and Ifan Huw Dafydd as Griffith. Directed by James Robinson.
