A married couple in their 40s, John and Laura Taylor desperately want to have a baby, but they are unable to have a lasting pregnancy. After attempting all other options, the couple hire a beautiful young woman named Anna, who agrees to become a gestational surrogate mother for the Taylors. After Anna has a doctor's appointment, her boyfriend, Mike, does not pick her up, causing Anna to go to John's job for a ride home. That night, Laura receives an emergency phone call from Anna. John drives to her house seeing the police. It is then revealed that Mike assaulted Anna, leaving her face bloody and bruised. The police suggest Anna find another place to stay, and John invites her to stay at the couple's house for the time being. Anna starts to develop a fixation on John as the pregnancy moves further along. Anna's growing obsession interferes with what was a plan by her and Mike, to scam the couple by demanding money. When Mike pushes Anna to demand a ransom, she kills him.
