In 1913, three German shipbuilders were ordered to reassemble a steam ship on Lake Tanganyika. At the same time, Winston Churchill sends Commander Geoffrey Spicer-Simson to transport two dilapidated and incongruously named gun-boats, Mimi and Toutou, to the other side of the lake. Then World War I breaks out as the two sides are facing each other.
In November 1913, three German shipbuilders, led by master shipwright Anton Ru ter, were ordered by Kaiser Wilhelm II to dismantle a steam ship, send the parts to German East Africa, and reassemble it on Lake Tanganyi- ka. Their initial aim of getting the task done quickly and returning home to claim an excellent salary is quickly eclipsed by the enchantment of the exotic landscape, the governor's beautiful wife, and the violent machinery of colonialism. At the same time, Winston Churchill sends Commander Geoffrey Spicer-Simson to transport two dilapidated and incongruously named gun-boats, Mimi and Toutou, to the other side of the lake. When World War I breaks out the Germans and British are facing each other, and the boat-builders reluctantly find themselves having to fight under the unsympathetic Captain-Lieutenant Gustav von Zimmer.
