Complete Unknown

Alice (Weisz) an ever-changing woman in her thirties, is seen doing many professions in many parts of the world. She comes back to New York City after spending most of her twenties abroad under different identities to see Tom, an old college flame. While researching Tom (Shannon), she plans an interaction with his colleague, Clyde at their work cafeteria. She tells Clyde a story of her being a biologist and how she spent the last few years in Tasmania, Australia. She also explains why she is back in NYC. She tells him about a new species of a frog on Long Island. Clyde, obviously taken with Alice, invites her to Tom's birthday party. Read more on Wikipedia.
