We are all descended from migrants. Humans are, in fundamental ways, a migratory species, more so than any other land mammal. Migration is one of the most toxically controversial subjects of our day, but it is not only an issue of our age. Migrants are expected to assimilate and encouraged to remain distinctive; to defend their heritage and adopt a new one. They are sub-human and super-human; romanticised and castigated, admired and abhorred. 'Migrants' tells us that this is not a new narrative; this is the history of migration, which is part of everybody's backstory - for those who consider themselves migrants and those who do not.
