The documentary by Jean-Gabriel Leynaud portrays daily life in the small Congolese city of Numbi, which plays an important role for the western world, because workers mine coltan ore—indispensable for almost all our electronic devices—with their bare hands there. The film is screening exclusively at the Brotfabrik Kino, and on 4.6. at 19:00, producer Martin Kruse will be a guest.
