Anthony Farrant, a man defined by his history of deception and aimless wandering, finds himself employed as a bodyguard for the industrialist Krogh through the influence of his twin sister, Kate. As Anthony navigates the opulent but corrupt world of his sister's employer, his internal sense of ethics clashes with the ruthless demands of high-stakes finance.
