Silence speaks volumes in Code of Silence, the new British crime drama starring hearing-impaired actress Rose Ayling-Ellis along with Kieron Moore. At the heart of the suspense is an unusually endearing heroine, Alison Brooks (played by Ayling-Ellis), a working-class deaf canteen worker whose life takes an extraordinary turn when her remarkable lip-reading skills thrust her into a high-stakes police investigation targeting a dangerous criminal gang.
