One family drama which recounts with all power how it returned to the drama of a nation, when the event served the Hitler regime for what would become the most tragic humanity campaign: the annihilation of the newborn children's with disabilities, perceived as ignoble of the Aryan race. The madness of a father who definitely wanted a son potent enough to project the future of his family, urged the madness of a leader like Hitler who later would turn this idea in an obsession, the idea of a superior nation and race. Through this real event emerges the irony of the history itself that events that had changed the course of the fate of millions of people, have started from the crazy and banal idea of an unknown person in an unknown country. This movie brings to the surface the fact that large and shocking events of a nation and not coincidentally sometimes originate from the small passions of ordinary people. Throughout this painful historical irony comes in "Child K" through the use of a simple language but that clearly shows the usual life of a German peasant, switched to another dimension that runs simultaneously with the dramatic story of the peasant Richard Kretschkopf.
