This film is about the Great Lakes, how they were polluted and how they are being cleaned up. To tidy up the biggest body of fresh water in the world is a massive operation. The Great Clean-up documents some of the elements of this operation, including changes to legislation affecting the emission of industrial pollutants into the environment, on both sides of the Canada/US. border. The film's images speak very strongly for the importance of saving the Great Lakes from further pollution.
