A former Midwesterner, Dee Thornell moved to Alaska more than 25 years ago to pursue her life's mission: to care for wild and domestic animals of America's largest state.

Animal Planet documents her single-minded dedication to care for creatures like bald eagles, owls, chinchillas, beavers, iguanas, ox, moose and bears.
