Travel writer Frank Bures investigates the strange phenomenon of 'culture-bound' syndromes across the world: illnesses with a combination of psychiatric and somatic symptoms that are only considered to be a disease within a specific society or culture. They are found across the world within cultures and viewed from outside can seem both mysterious and odd. Bures has travelled worldwide and recounts strange cases such as voodoo death and penis theft. He investigates epidemics that seem like madness to outsiders but all-too-real to those experiencing them.
