This video-documentary gathers documentation and testimonies related to the thought and activity of Portuguese psychiatrist João dos Santos (1913-1987). It explores sound and visual language to create an audiovisual document that is also an artwork. Inspired by the radio programmes authored by psychiatrist João Sousa Monteiro and João dos Santos, and broadcasted by Rádio Comercial in the 1980s, the film breaks down key concepts on child development and society, constant interests of João dos Santos. The video has a documental character, because it is about a man, and an artistic character because it is a product of culture, that reflects on various aspects of the human condition.
