精简剧情：How far would you go to have a baby? Martin Compston, Sophie Rundle and Mirren Mack star in this emotional thriller about love, trust and the true cost of buying whatever you want. Dan (Compston) and Emily (Rundle) are crazy about each other. They live in a huge house in the nicest part of Glasgow and want for nothing. But they’ve been trying to have a baby for years with no success. When a chance encounter brings 18 year-old Kaya (Mack) crashing into Emily’s life, and it seems that just maybe, fate has brought them together. From the other side of town, Kaya is determined to make a life for herself. Experiencing the luxurious interior of Emily’s Range Rover, she quickly starts to get a taste for how the other half live. Back in her bare local authority flat, Kaya decides to change her future. She tracks down Emily and makes her an offer: she’ll be Dan and Emily’s surrogate, if they help set her life on track. She can change their lives, if they can change hers. But with only one embryo left, can Dan and Emily trust a teenage girl they barely know with their last chance to have a family?
