1905, the Belgian government sent a garrison of soldiers to the Congo to find a lost city, which would have once belonged to the great King Solomon, where an immense treasure would be found. However, a garrison of German soldiers, sent by the Kaiser in person, is also on the case. After having massacred an innocent village, the Germans get ahead of the Belgians but they hold on...until they arrive in a region where there are strange and very dangerous animals. In this lost corner, man is far from being the most dangerous!
