On a hot summer day, Pierre, a musician living in Paris, received an unexpected legacy, which seemed to be a turnaround in his fate. But soon, the turnaround turned from positive to negative. The inheritance was lost, and all my friends were out of town at this time. In a short journey, he became a tramp step by step. This is almost the most dramatic plot in Hou Mai's film. But this drama is only an opportunity in the film. The protagonist's social identity is lost in the embarrassment day by day, his dignity is almost gone, and everything around him is completely different. Here, things show relativity to people in different situations. The protagonist's circumstances can change the meaning of everything around him. The hawking of shops and vendors may usually be just noise in the protagonist's ears, but for the protagonist who has not enough to eat, it looks like a lure of desire; and the tourists around them are complacent in contrast to Pierre's curses on Paris. At the end of the film, the turning point falls on the protagonist again, and the protagonist still raises his arms and shouts as before. At the end, the pattern of the Leo constellation, which is constantly stacked and approaching, seems to correspond to the name of the film.
