The staff psychologist of the first Martian expedition, Laura Torres, unexpectedly receives telepathic messages from the depths of Space. Strange visions, saturated with fragments of earthly history, move her consciousness first to Ancient Egypt, then to the Middle Ages, then to our time. What is this? An encrypted message from an unknown super-civilization? To understand this, you need to watch the visions to the end. And the first of them tells about the wanderings of the Egyptian Un-Amun, who lived long before our era.
