Indonesia is calling. is an eight-part documentary series about the Netherlands and Indonesia between 1900 and 1950 - a period when the obviousness of the Netherlands' colonial rule over 'our East Indies' begins to falter. Resistance grows, Indonesians demand their right of self-determination and World War II and Japanese occupation are the prelude to a bloody war of independence. Major General Van Langen fights in that war, which lasts roughly from 1945 to 1950. It is one of the most controversial wars the Netherlands has ever fought. And Van Langen is not just anyone; he is among the leading figures on the Dutch side.
