Ethan McQuarry is a young lighthouse keeper on a tiny island, the rugged outcropping of easternmost Cape Breton Island on the Atlantic Ocean.
A man without any family, he sees himself as a silent vigilant, performing his duties courageously year after year, with an admirable sense of responsibility.
He cherishes his solitude and is grateful that his interactions with human beings are rare.
Even so, he is haunted by his aloneness in the world and by a feeling that his life is meaningles.
