This gripping Acorn TV Original features "a great cast and a twist-filled plot" (Evening Standard, UK). DS Nancy Devlin (Karla Crome) is a good cop with a secret: drug trafficker Frank Le Saux (Philip Glenister, Life on Mars) is like a father to her. Co-stars Robert James-Collier (Downton Abbey), Joe Absolom (Doc Martin), and Amanda Burton (The Commander).
