The Woman in the Wall plot
BBC's new six-episode drama centres on Lorna Brady (Wilson), a woman from a small, fictional Irish town named Kilkinure who wakes up one morning and discovers a corpse in her house.
The troubling thing is, Lorna doesn't know if she was involved in the killing or not because she has suffered with extreme bouts of sleepwalking in the decades after she was incarcerated in a convent and gave birth to her daughter Agnes, who was cruelly taken away from her.
This means she can't say for sure that she wasn't involved in the woman's death, and then Detective Colman Akande (Daryl McCormack) comes into her life for a seemingly unrelated crime and as he continues to be on her tail the pair become entwined in surprising ways.
As Colman works to find a murderer and Lorna searches for her daughter, the pair start to see their secrets become unravelled with both facing their past, and the dark side of Kilkinure, together.
