A young serial killer stalks the English countryside, focusing her economic rage on the wealthy families that employ her. An experimental law enforcement group hires a brilliant detective who uses his synesthesia as a means to find clues that no one else can see to bring an end to the killer's spree. Lawes' script splices scenes from the killer's genesis with the protagonist's current investigation. In essence, it is a dual origin story that shows how a disenfranchised youth becomes enamored with the power of death as well as exploring the trials and tribulations of a detective with mental health issues. The result is a fascinating dichotomy that slowly erodes as the two narratives approach collision.
