In the year 3500, when technology had prospered and become essential in human life, brilliant scientists researched and invented a new technology that allowed for the "copying" of memories from one person to another. The original purpose of this invention was to assist patients with memory loss, but it gradually transformed into a commercial service, where memories were traded as a form of entertainment or a way to escape one's own painful memories. Linh is a beautiful young woman who works as a "memory receiver"—she makes a living by purchasing memories that others do not want to keep. With a special brain, she can retain every detail that ordinary people cannot bear. Each memory she receives is a story, a piece of life. But one day, she receives a strange memory: a murder case... that has never been made public. And in that memory, the faceless killer is present—but the victim looks... very much like her. The deeper Linh delves into that memory, the more she uncovers buried truths, not only about the case but about herself: is she truly Linh—or just a product of patched-together memories?
