After four harrowing years on the Western Front, Tom Sherbourne returns to Australia and takes a job as the lighthouse keeper on Janus Rock, nearly half a days journey from the coast. To this isolated island, where the supply boat comes once a season, Tom brings a young, bold, and loving wife, Isabel. Years later, after two miscarriages and one stillbirth, the grieving Isabel hears a babys cries on the wind. A boat has washed up onshore carrying a dead man and a living baby.
