The sci-fi thriller Ex Machina, starring Oscar Isaac and Domhnall Gleeson, centers on Internet-search giant programmer Caleb Smith (Gleeson), who wins a competition to spend a weeklong vacation at a private mountain estate belonging to the company’s reclusive billionaire CEO, Nathan Bateman (Isaac). When he arrives, Caleb discovers the real reason he’s been sent. Nathan has chosen him to be the human component in a Turing Test—giving him the task of evaluating the capabilities and consciousness of Nathan’s new artificial intelligence experiment, the beautiful and seductive Ava.
