Inspired by real events, Landscapers explores the lives of convicted killers Susan and Christopher Edwards, and asks how this devoted and mild-mannered couple came to kill Susan’s parents and bury them in the back garden of their Mansfield home, in a crime that remained undiscovered for over a decade. This blackly comic, narratively playful true crime drama is based on extensive research, hours of interviews and direct access to the accused, who have always protested their innocence of murder.
