John and Laura Taylor are a successful couple living in New Orleans who have everything, except for a child of their own. After several failed attempts to conceive, they turn to surrogacy. They find Anna Walsh, a seemingly perfect young woman willing to carry their baby. As the pregnancy progresses, Anna moves into the Taylors’ guest house to ensure she is well cared for. Initially, things seem to be going smoothly, but as the weeks go by, Anna’s behavior starts to raise some red flags.

Anna becomes increasingly obsessed with John, developing a dangerous attraction to him. This infatuation leads her to display erratic and manipulative behavior, putting everyone involved under immense psychological strain. Tensions rise as Laura grows suspicious of Anna’s intentions and John finds himself caught in a web of deceit and seduction. The situation reaches a boiling point that threatens to destroy the Taylors' family and dreams of parenthood as they grapple with how to handle the increasingly volatile surrogate living under their roof.
