Documentary on naive Brazilian artist Moacir. Facing many problems, such as impaired hearing and speaking, abnormal bone formation and poverty, black artist Moacir lives in the National Park of Chapada dos Veadeiros, aloof and oblivious of outside world, and was discovered by director Walter Carvalho in the 1980s. He spends his days drawing marvellous works with his crayons, depicting human and fantastic beings, fauna, flora, his own inner visions, mystical themes and sex, with a trace of impressive primitivism and beauty. The film registers his daily life, and another Brazilian artist, Siron Franco, paying him a visit.
