When Jessica Brown Findlay landed the part of Lucy in ITV1's psychological thriller Playing Nice, she was a new mum herself — so the horror of discovering that the child you'd been raising wasn't actually yours was easy for her to imagine.
In the series, Lucy and husband Miles (James McArdle) discover that a hospital mix-up has led to them raising the biological son of Pete (James Norton) and Maddie (Niamh Algar), while Pete and Maddie unknowingly took home Miles and Lucy's child. Although the couples initially attempted to work out a way through the situation that would be in everyone's best interests, Pete and Maddie soon discovered that Miles and Lucy had set them up in a plan to gain full custody of both boys.
