Watch: See Martin Compston and Tuppence Middleton in the trailer for ITV thriller Our House
The series is an adaptation of the bestselling novel by Louise Candlish and tells the story of estranged husband and wife Fi and Bram Lawson (Middleton and Compston), and the house that still links them together.
In a taster of the drama to come, the trailer shows Fi's confusion as she arrives home one day to find a couple she has never met before moving in - except as far as she is aware, her house was never for sale.
After her split with Bram, they decided to keep on their dream home where they take turns in parenting their children for part of the week each.
But it appears Bram has sold the house without her knowledge during his days at the property and now he has gone missing.
The trailer hints at secrets kept by the couple as Bram tells Fi in one scene "anyone could have seen you", with her replying "they didn't, I was careful".
Bram also refers to money troubles, as Fi panics that she can't find him or get him to answer the phone.

Things are further complicated for the exes by two mysterious new love interests who show up in the trailer - charming Toby, played by Rupert Penry-Jones, and Honour (Buket Komur) who Bram becomes involved with.
Line Of Duty star Compston and Downton Abbey's Middleton are also joined by Weruche Opia (I May Destroy You) as Fi's best friend and neighbour, Merle.
Fi will discover some shocking secrets about the man she was married to, leaving her wondering whether she ever really knew him at all, while viewers are sure to be gripped by revelations about the estranged pair and their new partners.
The four-part drama is due to air this March on ITV.
