"Project "Vector"" is a secret organization engaged in the study of time and an attempt to transfer psychomatrix people to historical figures of the past. It prepares for the introduction of Tsarevich Alexander, the future Alexander III, an elderly historian, specialist at the end of the 19th century, Mikhail Konyaev. But as a result of an unexpected natural catastrophe, a temporal storm, another catastrophe occurs - a man-made one. And several people are already sent to the past: one falls into the body of Grand Duke Mikhail Nikolaevich, the second - into his son Alexander Mikhailovich. And this happens at the moment when Stepan Khalturin activates explosives in the Winter Palace. History has gone off track.
