Moment From Ex Machina
After Nathan is killed, Ava covers her body with skin and a wig, and wears a dress. She then reveals her true plans. She locks Caleb inside the room, triggers a power outage and leaves. She's free.
Caleb, a coder at the world's largest internet company, wins a competition to spend a week at a private mountain retreat belonging to Nathan, the reclusive CEO of the company. But when Caleb arrives at the remote location he finds that he will have to participate in a strange and fascinating experiment in which he must interact with the world's first true artificial intelligence, housed in the body of a beautiful robot girl.
