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.
As WWI rages in Europe, the Kaiser's pleasure cruiser and two dilapidated British gun-boats face-off in the heart of America.
