The series is about the diaries of a teenage girl in Glasgow. This teenager is still facing a new path in her life, especially when she agrees to carry a child to the couple Dan and Emily. This teen started to change the course of the couple's life unexpectedly.
Some of the show's plotlines and future reveals are obvious right from the get-go, but perhaps that's the point - we're watching a desperate couple walking into what appears to be a trap of their own making.
Not one of the actors is putting in a bad performance and the plot isn't outlandish compared with some, but there's still something unengaging about it.
Nicole Taylor is the writer behind the Bafta success Three Girls, and it shows: in this, she's given us not just a twisty, whose-motive-is-it-anyway thriller but also, so far, a pointed exploration of the rights and wrongs of surrogacy.
Helped by the intensity of Mirren Mack's performance. She's terrific casting here, compelling to watch and skirting the border between earnest and unhinged.
For quite a lot of the first episode I wasn't wholly sure whether I was watching a thriller at all, or whether it was all supposed to be more about middle-class hypocrisy, or underclass desperation, or parenthood, or fertility, or what.
