This work tells a science fiction story that takes place in the future world. When one day, people's wealth can be increased or decreased at will through mobile phone APP, are you willing to exchange other things for it? And this "other thing" may be your health, or your lover, or your life? This work makes extensive use of film and television special effects technology to simulate the sense of technology in the future society. In today's increasingly mature science and technology, it is expected that this work will bring some reflection to people.
