Through footage from 16 security cameras which served initially for a self-surveillance video-diary, we are swept into the pro-paranoia world view of “Dutch Cocaine Factory”. At the heart of the film resides Arend ter Horst, a 63-year-old cocaine addict who betrays all the signs of acute paranoia. It becomes very clear early on in the film that this paranoia is far from misplaced. Groenendaal commences a documentary journey with Arend that reveals the terrifying degree of surveillance – or “digital chasing” as well as the history and the relevance of cocaine for Dutch society. En route, she tells the story of the original Dutch cocaine factory which in the 1920s imported up to 2 million pounds of cocoa leaves per year to supply an extremely profitable – and perfectly legal – industry. What happened in the 1920s? What happens today when you are a suspect in the drug business? Who is controlling the controllers? "Dutch Cocaine Factory" deals with all these questions and more.
