Jimmy Kokupe is a miracle: he's been cured. But he still carries the stigma, which makes life back on the mainland dangerous and lonely. To find a refuge, he's returned to the camp to care for his friend, fellow patient old Will, and disturbed young Charley. Healed of his physical ailments and dreaming of the girl he once planned to follow to a new life in Australia, Jimmy meets 'the lady', the island caretaker's beautiful but troubled wife who brings their food. Can she help Jimmy forget his difficult past and overcome his own prejudices towards his mixed parentage, and find the courage to risk living in freedom?
