This documentary - at times funny, at other times heartbreaking - is ultimately the inspiring story of how Los Angeles residents act to rescue and protect animals that suffer as a direct result of human abuse, neglect, or carelessness. Living By Instinct features Duncan the pig, Fluffy the turtle, and other lucky animals, in addition to the people who have been actively involved in their rescue, rehabilitation, and nurturing. Focusing on several Los Angeles residents of different ages, genders, and backgrounds, the film shares how these oft-misunderstood individuals devote much of their energy to rescuing animals in need.
