The story of this movie is about memory erasure of a couple who once loved each other but now, suffer from the memories of their love. Joel Barish (Jim Carrey) decides to erase his memory about his girlfriend, Clementine Kruczynski (Kate Winslet), after he discovered that she had removed all of her memories about him. He goes to see Dr. Howard Mierzwiak (Tom Wilkinson) of Lacuna Inc., a firm that helps people erase their painful, heartbreaking memories with a special brain map processing, and asks the doctor to erase his memory. However, while the memory erasure is ongoing, he faces with their earlier memories that are so passionate, sweet and precious that they should never be deleted. Although Joel tries to wake up and stop getting rid of her from his mind, Dr. Mierswiak and his employees keep going on the process. Joel eventually gets to the last memory, disappearing with the last words of Clementine saying, “Meet me in Montauk.” Other than the story of main characters, the staff members of Lacuna Inc. such as Mary (Kirsten Dunst), and Patrick (Elijah Wood) also have some related stories which will be a key for the ending of this movie.
