Director Ulyana Makarskaya received a tempting offer - to make a film about the northern polar station. An exciting adventure and a good salary await her. And of course, she will make a film that will certainly win a prize at a prestigious festival! But these are still dreams; in reality, she is met by frost, a blizzard and seven polar explorers who can’t wait to return to the mainland... Unexpectedly, the station received an SOS signal from a nearby American observatory. Polar explorers discovered that all their neighbors were dead, and it was completely unclear what happened to them... Ulyana’s new colleagues seized from the observatory the diary of Captain Neverov, who explored the North at the beginning of the last century. The girl began to study it, and meanwhile strange things were happening at the station - the employees began to hallucinate. Ulyana tried to hold on, but soon her long-dead father came to her... What kind of power did they disturb and how to save their little closed world from it?
