Over Lake Baikal, the unknown and unknown opens the door. People have been given gates, but where do they lead? The planet is infected with anomalies, alien flora and fauna are destroying cities. The world is in panic. The question of leaving or staying breaks lives. Some people pin their hopes on the colonization of Mars, while others continue to save the earth. To preserve the earth's biome, a huge botanical garden is being built in the Gobi Desert. It is there that scientists from all over the world are conducting an experiment to create a unique environment for the coexistence of terrestrial and extraterrestrial life forms. Perhaps this is the very last hope for humanity, when suddenly, inside a sterile, sealed station, scientists begin to kill each other.
