M – Eine Stadt sucht einen Mörder

In Berlin in the early 1930's, children are being lured to their death by a psychopathic killer. In the space of a year, 8 children have been murdered. The police have redoubled their efforts to find the guilty man but have yet to find him and citizens are beginning to dispense their own justice on otherwise innocent people. The heads of the city's criminal element are paying a high price due to the increased police presence and decide to find the psychopath on their own. They approach the beggars union to have their members blanket the city with spies. They're successful in finding the killer and put him on trial in their own special court but the police make progress and have their own views on how justice should be administered.
