Salman Luban, a young Belarusian, was sent to the Calanca Valley by the Red Cross in 1917. In this remote area of Italian-speaking Graubünden, he found his calling – and never saw his homeland again until his death in 1954. Salman Luban's grandson sets out in search of his grandfather and a nearly lost form of medicine that, according to his genealogy, viewed the human being as a whole.
