1973. In a close-knit community on Ireland’s west coast, a baby is found abandoned on the beach. Named Brendan by Ambrose Bonnar, the fisherman who adopts him, the boy will become a source of fascination and hope for a town caught in the storm of a rapidly changing world.
Ambrose, a man more comfortable at sea than on land, brings Brendan into his home out of love. But it is a decision that will fracture his family and force this man – more comfortable at sea than on land – to try to understand himself and those he cares for.
