Her

In a near future Los Angeles, Theodore Twombly is a lonely, introverted, depressed man who works for a business that has professional writers compose letters for people who are unable to write letters of a personal nature themselves. Unhappy because of his impending divorce from his childhood sweetheart Catherine, Theodore purchases an operating system upgrade that includes a virtual assistant with artificial intelligence, designed to adapt and evolve. He decides that he wants the AI to have a female voice, and she names herself Samantha. Theodore is fascinated by her ability to learn and grow psychologically. They bond over their discussions about love and life, such as Theodore's avoidance of signing his divorce papers because of his reluctance to let go of Catherine.
