In 1986, Lenora retrieves Martin from protective exile in Angola to assist her with an operation selling a shipment of West German weapons to the South African Army.

Lenora and Martin make arrangements to bring the weapons shipment into Angola. To pay the guide, Gary Banks, Martin sleeps with the West German Trade Commissioner's wife Brigitte Winkelmann and steals her diamond necklace.

Gary takes Martin, Lenora, and a hidden team of rebels into the oil refinery under the pretense of selling the weapons to Major Kalumba. Martin negotiates the sale, and once they have the payment, Gary holds Kalumba at gunpoint, planning to leave with the money, the weapons, and three tankers of diesel, after which the rebels will bomb the refinery.
