A meditation on isolation, faith and survival inspired by real historical events, as a trio of seventh-century monks found a monastery on an impossibly remote island.

Three men vow to leave the world behind them and start anew...

In seventh-century Ireland, a scholar and priest called Artt has a dream telling him to leave the sinful world behind. Taking two monks - young Trian and old Cormac - he travels down the river Shannon in search of an isolated spot on which to found a monastery. Drifting out into the Atlantic, the three men find an impossibly steep, bare island inhabited by tens of thousands of birds, and claim it for God. Their extraordinary landing spot is now known as Skellig Michael. But in such a place, far from all other humanity, what will survival mean?
