Dr M (Claude Chabrol, 1990)

There is a massive wave of suicide in Berlin, some of them causing accidents with hundreds of casualties on both sides of Berlin. The population believes it is caused by a virus and there is an exodus of Berliners that travel through Club Theratos, an agency promoted by the model Sonja Vogler in several screened billboards, television and magazines. In West Berlin, Lt. Klaus Hartman, who lost his wife Nina two years ago after committing suicide, and his partner Sgt. Stieglitz are relentless in the investigation. He believes that the suicides are murders indeed. When the snoopy journalist from Eastern Berlin, Moser, breaks in the Club Theratos, he finds that the owner Heinrich Marsfeldt is the responsible for the deaths, and is using his stepdaughter Sonja to hypnotize the population. Further, he intends to use the popular show of the host Veidt to induce the viewers to commit suicide. Will Hartman and Sonja be capable of stopping his evil plan?
