The play is based on a French film in 2004. In a mountain city overlooked by a huge dam, one day, several lost people of different ages and from different places found their own way home. What they do not realize is that they have been dead for many years, but they have not grown old, and no one is waiting for their return. They try to go back to their own lives. Gradually, they find that they are not the only returnees, and their return is causing more and more interference to the order of the world. Or is this just a prelude to a bigger upheaval?
