The men of Chemics International lead a quiet life. However, this is cruelly disrupted by an industrial accident in which a toxic substance is released. Some workers are killed; many others are irrevocably contaminated and may suffer permanent injuries. The management, government, press and unions do not react, seeing this as an unfortunate incident. When one of Herman and Jef's best friends also dies, they have had enough. Together they made an ultimate attempt to reveal the truth to the outside world.
Unfortunately the movie De Proefkonijnen is not yet available on HBO Max.
