In the Sign of the Cross 1983 on netflix

Fictional story of a traffic accident that triggers a catastrophe near a small village in 1990. A liquefied gas truck collides with a transport truck carrying radioactive material for reprocessing. An accident that was never thought possible by human standards. The radioactivity released must be contained at all costs. Not only the catastrophic consequences of the radiation, but also the panicked, irrational and inhumane behavior of those trapped in the village and the German army are portrayed in an almost unbearable way in this film.
