Widowed crime writer Tom Kennedy (Adam Scott) grew up knowing the chilling nursery rhyme about a boogeyman who snatches the young and innocent from their homes. According to the verse, 'If you're lonely, sad, and blue, the Whisper Man will come for you.' When Tom's eight-year-old son Jake (Acston Luca Porto) is abducted along with other children, the writer is reminded of the case of a convicted serial killer known as The Whisper Man. His estranged father, Pete Willis (Robert De Niro), a retired police detective, put Frank Carter (Michael Keaton) behind bars but Jake's disappearance compels the distraught family to revisit the evidence. Detective Amanda Beck (Michelle Monaghan) leads the live police investigation in a taut thriller directed by James Ashcroft, based on Alex North's bestselling novel.
