Twenty years ago, a serial killer, nicknamed the Whisperer by the press, created a real hell for the residents of the small English town of Featherbank. He kidnapped little boys, whispering promises and promises through their open windows. And then he brutally killed. The killer was caught, and it has been many years since he was put behind bars. Peace reigned in the town. That is why writer Tom Kennedy and his son Jake decided to move here. After a recent tragedy in their family, peace is just what they need. And then another boy disappears in the city. It became known that the day before he heard someone whispering outside his window. The old horror seems to have returned... But who did it - if the maniac is in prison? And who will be the next victim? Maybe Jake?
