A man finds himself on a desert island, all alone, building a comfortable little world for himself. Suddenly, in the burst of some machine coming from the sky, an individual falls alongside him who, with the same voice, asks for his help and calls himself heir to civilization and its hierarchical power. He calls himself the Emperor of Assyria. The two characters strive to create multiple dramatic situations during which each of them maliciously affronts the other. As they give each other change, they exchange their roles at any moment.
