Martin Compston (Line of Duty) and Sophie Rundle (Peaky Blinders, Bodyguard) star in this suspenseful Scottish drama about a wealthy couple who would do anything to have a baby. When Emily (Rundle) accidentally hits Kaya (Mirren Mack, Sex Education), a down-on-her-luck 18-year-old, with her car, the two make an instant connection. After learning about her desperate situation, Kaya offers to carry Emily's last embryo as a surrogate. Although Emily's husband, successful businessman Dan (Compston), warns about the legal and moral implications of such an agreement, the women are adamant. But as buried secrets emerge about Kaya's past, Dan and Emily start to wonder if they're the ones being used.
