Mirage

The main character is a robot which looks like a human. The setting is deep in the water in the future world. He is collecting water to live but there is few. He gets it by squeezing a flower and bamboo. Finally he finds a fruit which is filled with water and there is a gold fish in it. To get water he is about to kill the fish. It seems he thinks only about getting water, about himself. Also that world does not look like comfortable. I think the theme is that our endless desire will make the world worse to live in. Even water, one of the most familiar natural sources, is in short in this film.
