A 50-year-old writer shares his Manhattan loft with 1,200 turtles, including five species extinct in the wild.

A decade ago, after an epiphany at a New York restaurant, Richard Ogust began dedicating his time and resources to rescuing endangered turtles - confiscating hundreds bound for Southeast Asian food markets. When the filmmakers catch up with the 50-year-old writer, he's sharing his Manhattan loft with 1,200 turtles, including five species extinct in the wild. But his growing "ark" and preservation efforts are threatening to exhaust him, mentally and financially. With luminous images and a haunting musical score, "The Chances of the World Changing" documents two years in the life of a man who finds himself struggling to save hundreds of lives, including his own.
