The Greyness of Autumn follows the final days of the life of Danny McGuire, an ostrich living in Scotland. Danny's life is suddenly turned upside down when he loses his job and his girlfriend in the same day. As Danny struggles to reinvent himself in a society that treat him as a second class citizen, he questions whether there is much point living in a world that will never see past the feathers.
