Racoon Nation

A look at urban raccoons, which are commonplace in such big cities as Toronto, New York and Chicago. In Toronto, night-vision cameras and radio collars provide a glimpse of one raccoon family's life. The documentary also details the damage the critters have caused in Japan, where they were imported as pets during the 1970s, and in the German town of Kassel; and includes comments from a biologist who believes city life is spurring an evolutionary spurt in their mental prowess.
