The year is 1903, and the garrison of Yangambi on the banks of the River Congo is under the command of Captain Lalande Biran. The captain is also a poet whose ambition is to amass a fortune and return to the literary cafes of Paris. His glamorous wife Christine has a further ambition: to own seven houses in France, a house for every year he has been abroad. At Lalande Biran's side are the ex-legionnaire van Thiegel, a brutal womaniser, and the servile, treacherous Donatien, who dreams of running a brothel. The officers spend their days guarding enslaved rubber-tappers and kidnapping young girls, and at their hands the jungle is transformed into a wild circus of human ambition and absurdity. But everything changes with the arrival of a new officer and brilliant marksman: the enigmatic Chrysostome Liege.
