USSR: 2026

A young medic, Dmitry Kuprin, from a small town suddenly finds himself in the body of a cosmonaut from a parallel universe where the Soviet Union still exists. In his familiar reality, he struggles with personal difficulties; in the other, he strives to protect Earth from a fragment of a meteorite discovered on the Moon. The intertwining of friendship and betrayal, cosmic adventures and the criminal underworld, beer for a hundred rubles and sausage for two ninety, mysterious handlers who control the chain of worlds and play dangerous games—how do you sort it all out? And, above all, how not to lose your own identity?
