A State sanatorium has just collapsed killing 128 children. When the construction of the building was being planned, an eminent public works specialist, Professor Calame, had predicted the catastrophe. However, his warnings went unheeded. It is in the interest of many politicians implicated in the affair that this expert's report should disappear. The minister, Auguste Point, had the report in his possession for a few hours, but it was stolen from him. He can't make a statement to the public who would immediately accuse him of having destroyed the document to save himself and his colleagues. In desperation he asks Superintendent Maigret to discreetly recover the report, or to at least find the thief. Directed by Christian de Chalonge, 2002, color. In French with English subtitles.
