In 1100AD a monk named Henri hears voices telling him he is Saint Martin of Tours. Today we would recognize it as an illness called schizophrenia. When his behavior becomes a costly embarassement to church and King,a unique solution is found. Thus begins a journey through Europe's inland waterways at the dawn of medicine and psychiatry. Henri is joined by other social outcasts, as this ship of fools is guided by the unwilling but honorable Count Edourd. Eventually they find acceptance in the same place others have sought peace and prosperity; Jerusalem. Based on extensive historical research, the lives of those who suffered from mental illness in 1100AD and those who live with the illness today challenge our beliefs about mental illness.
