The Light In The Hall | Preview (Channel 4)

Drama starring Joanna Scanlan, Iwan Rheon and Alexandra Roach, about a woman still grieving for her daughter who disappeared 18 years earlier.

Sharon Roberts (Scanlan) has spent nearly two decades searching for her daughter Ela's (Ella Peel) body. Shortly after she vanished, mild-mannered gardener Joe Thomas (Rheon) was arrested and charged with her murder after Ela's DNA was discovered in his caravan.

Joe confessed to her murder but refused - or could not explain what - he did with the body. Now Joe is being considered for parole, and if he is released, Sharon's greatest fear may be realized: she will never get Ela's body back and the past will torment her for the rest of her life.

Journalist Cat Donato (Roach), who's originally from the same town, has always been interested in Ela's murder. It's a very personal story for Cat, who has always kept an eye on the story, and the news that Joe is due for parole prompts her to return home to write an in-depth article and discover the truth one and for all.

But will she be welcomed back to the town where she grew up? Meanwhile, Sharon is also desperate for answers - and she'll go to any lengths to get them...

The Light In The Hall begins Wednesday 4th January at 9pm on Channel 4.
