Dark of the Sun
by Wilbur Smith
In the mid-1960s, mercenary Bruce Curry is publicly hired by Congolese President Ubi to rescue European residents from an isolated mining town about to be attacked by rebel Simbas in the Congo. However, his real mission is to retrieve $50 million of diamonds from a mine company's vault. Curry's subordinates include his friend Ruffo and alcoholic Doctor Wreid. He also reluctantly recruits ex-Nazi Henlein because he needs his military expertise and leadership skills.
Ubi gives Curry a steam train and Congolese government soldiers. However, as the mission is in violation of UN accords, the train is attacked and damaged by a United Nations peacekeeping plane. At a burned-out farmhouse, they pick up a traumatised woman named Claire, who watched her husband being hacked to death by Simbas. Meanwhile Henlein begins to cause trouble because he knows about the diamonds and resents Curry's leadership. He casually kills two children for being possible Simba spies and starts making advances towards Claire. When interrupted by Curry, the German attacks Curry with a swagger stick and a chainsaw. Only Ruffo is able to stop Curry from killing Henlein in a murderous rage.
Further complications arise when the mercenaries reach the mining town. First, the diamonds are in a time-locked vault delaying the train's departure. Second, Dr Wreid insists he can't abandon a pregnant woman at a nearby mission hospital. Reluctantly, Curry agrees to let the doctor stay behind.
As Curry waits anxiously for the vault to open, the Simbas arrive and begin attacking the town and station. Eventually, the train, loaded with the diamonds and residents, slowly leaves under small arms fire. However, just as it's getting out of range, a mortar round destroys the coupling between the last two carriages. The last coach - carrying the diamonds and most of the Europeans - is left to roll back into the Simba-held town as the rest of the train steams away.
Curry and Ruffo set out to retrieve the diamonds from the rebels at nightfall. Using a Simba disguise, Ruffo carries Curry's lifeless body into the town's hotel where harrowing scenes (for the film's time period) include murder, torture and male rape. A diversionary attack by surviving Congolese soldiers gives them the opportunity to get the diamonds and escape in vehicles. When they run low on fuel, Curry leaves to find more. Henlein uses his absence to kill Ruffo in the mistaken belief that he has the diamonds. When Curry returns to find his friend dead, he pursues Henlein in a murderous rage and kills him after a vicious fight. Back at the convoy, with his job done, Curry reflects on the type of man he is before turning himself in for a court-martial to answer for his actions.
