February 1942. With the Nazis triumphant in Europe, North Africa and much of the USSR, control of the shipping lanes off the southern tip of Africa is an Allied imperative. At the urging of Prime Minister Jan Smuts, South Africa's parliament has narrowly voted to join the British war effort, but the country remains bitterly divided. Feisty university student Anna van der Vliet returns to her family farm near Cape Agulhas during the holidays. Noticing strange comings and goings in the area, she begins to suspect that her father, a prominent Member of Parliament, may be involved in a clandestine operation to aid the enemy.
