Dr Harry Lynd heads a UN medical team sent into Portuguese Mozambique to investigate an epidemic of river-blindness which has become rife amongst the villagers. As they search desperately for the source of the plague of blackfly which carry the deadly, blinding oncho worm, the barbaric bush war between the Portuguese and guerilla armies flares up into bloody violence all around them - and they become torn between the needs of dying men and the dictates of the government.

The brutal war also casts a shadow over Luke Magellan, who is on his annual visit to Mozambique. For Luke, English heir to the vast cashew tree plantations, is haunted with guilt at the way in which the Company has exploited the natives. He resolves to avenge the cause of one of his own employees, a girl of mixed blood, savagely mutilated by a young Portuguese soldier. But as the war moves towards its dramatic climax, Luke discovers that his desire for justice has led him into the tortuous snares of political intrigue, and mortal danger.
