Sunset is a documentary film set in the “Dr Simo Milošević” Institute for Physical Medicine and Rehabilitation in Montenegro, the last active state-run health resort of its kind from the former Yugoslavia. Through the observation of daily cycles of therapy, disciplined work, and repetitive movements, the film follows a temporary community shaped by shared routine, physical closeness, and care, within an ambience of bygone modernism.
