1976 film by Clive Rees

A pair of children befriend an eccentric old man, who lives isolated on the far shore of their island home. But it turns out that the old man knows a terrible secret about the island and the whales who sometimes come. Meanwhile WWI is making life hard in the village.

A group of Slave workers, drafted by the Nazis to help construct their coastal defences in 1944, are trapped in an underground bunker when the Allies land at Normandy on D-Day. They find huge stores of food, but not enough candles. The slow dying of the light parallels their increasing boredom, illness, and jealousy during their entrapment. Based on the Novel 'Le Blockhaus' by Jean Paul Clebert
