chunk: The film opens as the shy, soft-spoken Joel Barish and the unrestrained free-spirit Clementine Kruczynski begin a relationship on a Long Island Rail Road train from Montauk, New York to Rockville Centre. They are almost immediately drawn to each other despite their different personalities, though both had felt the need to travel to Montauk that day. Although they do not realize it at the time, Joel and Clementine are, in fact, former lovers, now separated after having spent two years together. After a fight, Clementine had hired the New York City firm Lacuna, Inc. to erase all of her memories of their relationship. Upon discovering this from his friends Rob and Carrie, Joel was devastated and decided to undergo the procedure himself, a process that takes place while he sleeps.
