One year ago a small budget documentary was premiered at the HotDocs film festival in Toronto. The film followed the journey of a photographer – Jo-Anne McArthur – as she explored the exploitation of animals in modern society.

In the year that passed, The Ghosts in Our Machine has become a staple in the work of advocates everywhere. With harrowing – yet not gruesome - scenes inside factory farms and fur farms, Ghosts is a powerful yet palatable look into a world many try to ignore.

To celebrate this one year landmark and the release of The Ghosts on DVD and the iTunes Store, Jo-Anne McArthur joined Defender Radio for a candid conversation.
