ITV has commissioned a new psychological thriller, which sees two couples discover their toddlers were switched at birth in a hospital mix-up, and face the horrifying decision of what to do, which has been titled Playing Nice.

On behalf of Rabbit Track Pictures, Kitty Kaletsky and James Norton said: "Playing Nice was the first book we optioned after launching Rabbit Track, and we feel immensely proud of the project it has become.
"To be working with ITV, StudioCanal, wonderful Grace Ofori-Attah, visionary Kate Hewitt, our unbelievable cast and the whole rest of the production team is a huge privilege. We're thrilled and very excited."
According to the synopsis, the series follows two couples who face "a horrifying dilemma: do they keep the sons they have raised and loved, or reclaim their biological child?"
It continues: "Living a waking nightmare, Pete (James Norton) and Maddie (Niamh Algar) are jettisoned into the world of the other couple; Miles (James McArdle) and Lucy (Jessica Brown Findlay).
"At first, it seems all four are agreed on a solution, but it soon becomes clear that hidden motives are at play.
"How far can each couple trust the real parents of their child – or even each other? As Pete and Maddie are stretched to breaking point, they realise they will stop at nothing to keep their family together."
Speaking of the series, Ofori-Attah added: "It has been an absolute privilege to adapt JP Delaney's gripping novel for the screen. I am thrilled to be working with Rabbit Track and StudioCanal, as well as our incredible cast and production team.
"I'm also excited to be partnering with ITV again on my second drama series, and can't wait for Playing Nice to hit TV screens next year."
Further casting for the show is yet to be announced.
