Code of Silence Season 1

At the heart of the series is Alison Brooks (Rose Ayling-Ellis), a smart and determined Deaf woman. Having spent years working in a police canteen and secretly observing conversations, her life takes an unexpected turn when her exceptional lip-reading skills catch the attention of DS Ashleigh Francis (Charlotte Ritchie) and DI James Marsh (Andrew Buchan). Recruited for a covert operation, Alison is tasked with surveilling a dangerous gang as they plot a high-stakes heist, thrusting her into a world of crime, deception, and risk like never before. As she deciphers their secret exchanges, Alison becomes an invaluable asset to the case, but the deeper she gets, the more perilous her role becomes. When she crosses paths with Liam Barlow (Kieron Moore), the gang's newest recruit, an unexpected and dangerous bond forms between them, one that threatens to expose her true identity while pulling her further into the criminal world.
