The period from 1965 to 1971 in Slovenia—then a republic of socialist Yugoslavia—was marked by the avant-garde art movement known as the OHO Group, which has inspired and continues to inspire many artists, including Marina Abramović. OHO is regarded as one of the most fascinating, complex, and significant examples of post-war avant-garde art in Central and Eastern Europe. This documentary film, rich in never-before-seen materials, comprehensively presents this inspiring phenomenon of intertwining art and life for the first time.
