The Underground Railroad

Does anyone know if there has been a specific film about how it was organized, the routes, experiences, etc.? Not just references to the UR but a real story. I have read snippets here and there but I would like to see a dramatization about the various abolitionists that organized it, and how slaves fared after reaching Canada. It doesn't seem that much has been portrayed about people of African descent in Canada. I'd also like to see a drama about how the indigenous peoples of Canada were treated by the European invaders. I've see 2 or 3 films/documentaries that tell the truth about how the Europeans abused the Aborigines in Australia. I've seen enough "pioneer" crap. Time for stories that tell the true facts, not a whitewash of history.
