The story in letters. A chronicle of long-distance love and life in a confined space. The earth is dying. Trouble came from where we didn't expect it. The people themselves let her into their green house. In an attempt to save the human race, a group of people are sent into orbit. They will have to wait out the death of the Earth in space. And return to restore the planet. Evgenia Svetlova became one of the residents of the life support station. But her heart remained on the dying Earth. Together with Misha, to whom she writes regularly. Not being able to send a letter.
