Mammoth Screen (Code of Silence) adapts Liz Jensen’s bestselling novel, delivering a powerful thriller about climate catastrophe that crackles with wit, danger and foreboding. In a small South Wales town, we meet our complex, captivating and reluctant protagonists. Recovering from a life-altering car crash and adapting to a new existence as a wheelchair user, forensic psychologist Gabrielle Fox takes a job in a high-security psychiatric hospital. Here she meets her new patient, 17-year-old Bethany Krall. Convicted of murdering her mother Karen, Bethany has always protested her innocence and tells Gabrielle she’s receiving psychic messages that reveal the truth about her mother’s murder and foretell natural disasters.

Meanwhile outside, Britain is sweltering in the grip of an apocalyptic heatwave. Temperatures are rocketing, and a battle rages between climate activists and those wanting to ditch unaffordable green promises. Living in this dangerous tinderbox, Gabrielle is shocked when Bethany's predictions of catastrophic floods and storms appear to be coming true. As the stakes multiply, is Bethany just a highly manipulative psychopath or can she really see a global cataclysm on the horizon?
