Ava

An artifical intelligence created by tech genius and Blue Book founder Nathan Bateman and housed in a robotic female body. At first she looks obviously artifical with transparent abdomen, legs, arms, and skull, having only a lifelike face to present the illusion of being human. She was designed to read and make facial expressions, converse, and move naturally, and despite being recently made has the personality of an adult woman. She has never been allowed to leave the room where she is kept, although she has secondhand knowledge of the outside world. She is the subject of an evaluation by Caleb Smith, a Blue Book employee selected by Nathan. This evaluation is to judge whether Ava is genuinely capable of thought and consciousness, and whether Caleb can relate to Ava despite knowing she is artifical. Since Caleb is the first person she has met besides Nathan, she takes great interest in him, and soon begins to act like she has romantic feelings for him. However, during a power outage she suddenly tells Caleb not to trust Nathan, and begs him to help her escape. As the tension of the film escalates, there are signs that Ava may have an agenda other than simple escape from captivity.
