Line of Duty's Martin Compston is to star opposite Downton Abbey's Tuppence Middleton in Our House, an ITV adaptation of the best-selling Louise Candlish book of the same name.
The cast also includes Rupert Penry-Jones (Whitechapel), Weruche Opia (I May Destroy You) and Buket Komur (Honour). Sheree Folkson (Bridgerton, American Horror Story) is behind the lens as lead director.
Teasing the twists ahead, ITV said: "Fiona Lawson (Middleton) arrives home one day to find strangers moving into her house. With all her family's possessions and furniture nowhere to be seen, Fi believes there's been a huge mistake and insists her home isn't for sale. With events spiralling beyond her control, her panic rises as she can't reach her estranged husband, Bram (Compston).
"As she reflects upon the safe space in which she and her family had made a life together, Fi begins to peel back the layers of her relationship and discovers her husband has disappeared. With her life shattered, she realises the secrets and lies have only just begun."
Compston described the Our House scripts as "genuinely thrilling, packed with twists and turns that kept me guessing until the end".
"What struck me about Our House is its immense relatability; it's a story where you catch a glimpse of yourself in the characters, and you get the chilling realisation that what happens to Fi could happen to anyone," said co-star Middleton.
