Fashion designer Amy Powney of the cult label Mother of Pearl is a rising star in the London fashion scene. Raised off-the-grid in rural England by activist parents, Amy has always felt uneasy about the devastating environmental impact of her industry. When she wins the coveted Vogue award for Best Young Designer of the Year, which comes with a big cash prize, Amy decides to use the money to create a sustainable collection from field to finished garment, and transform her entire business. Over the following three years, her own personal revolution becomes the precursor of a much bigger, societal change.
