During the night between 5th and 6th December 2007 a serious fire invests line 5 of the establishment ThyssenKrupp (Turin, Italy). The families, friends and colleagues of the seven victims recount the tragic circumstances of that night and their lives of survivors. The film gives voice to anger, questions unanswered about how he could have happened, the pain of victims' relatives and the accusations to the managers of the factory. The film begins with a prologue in black and white in which actors act the parts of the victims' relatives: they remember the moments before the tragedy.—Marco
