The trailer for Vicky McClure's new psychological thriller, Insomnia, has been released - and viewers are in for a chilling watch.


As the trailer begins, McClure's (Line of Duty, Trigger Point) character, Emma Averill, is putting her son to sleep, joking that the monster living in their house is her - and as the 90-second clip continues, that soon becomes more truthful than she anticipated.

Throughout the video, Emma begins to show signs of insomnia, unclear on the events taking place around her.

The series, based on the novel of the same name by Sarah Pinborough, follows a career-driven woman whose life takes a turn when she finds herself ensnared in a "web of sleeplessness, echoing her mother's own past struggles", days before her 40th birthday, just as her mother had done before suffering from a violent psychotic breakdown.

The synopsis continues: "As the past resurfaces, so do haunting doubts and fears. With her mother's sudden hospitalisation, the return of her estranged sister, and an unnerving sense of being watched, Emma is thrust into a realm where truth is not what it seems... the past never sleeps."

As the trailer comes to an end, a voice can be heard repeating: "There is only one monster in this house, and do you know who it is? It's me."
