The Willis family continue their journey to Toronto, while the eastern ports and cities of British North America were overwhelmed by typhus-infested refugees who caused health crises wherever they went. The programme also looks at the heroes of the young city of Toronto as they absorb the famine refugees. Portrayed in the film are Dr. George Grassett, who was the Chief Medical Officer at Toronto's Fever Sheds, Toronto's Emigrant Agent, Edward McElderry, Nurse Susan Bailey, who also worked in the Fever Sheds and Bishop Michael Power who is the chief hero of Toronto's summer of sorrow in 1847 – responsible for building the fever sheds and hospital that saved thousands of the refugees – and finally dying himself from Typhus – contracted from his time in the fever sheds.
