ITV has dropped the chilling trailer for its upcoming psychological thriller, Playing Nice – and it looks seriously good.

James Norton (Happy Valley) and Niamh Algar (Malpractice) star in the series opposite James McArdle (The Mare of Easttown) and Jessica Brown Findlay (Downton Abbey) as two couples who discover their toddlers were switched at birth. 

Based on the best-selling novel by British thriller author JP Delaney, the Cornwall-set series follows the two sets of parents as they face a horrifying dilemma: do they keep the sons they have raised as their own or reclaim their biological child?

"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."

The trailer sees parents Pete and Maddie happily playing with their little boy on the beach before their seemingly carefree life is suddenly upended by some shocking news. "There's no easy way of saying this, but we have reason to believe Theo is not your biological son," the couple are told. "We think you left the hospital with another couple's son and they left with yours."
