The film starts with a brief review of the history of Antarctic exploration by scientists of Britain, Russia. Norway, Australia and America.
In January, 1956, the first Soviet scientific expedition arrived at the coast of Antarctica and built the observatory-town, "Mirny". We see episodes from the construction of the observatory, the work of the meteorologists, hydrologists, chemists, geologists and biologists on the eastern coast of Antarctica.
We study the flora and fauna of Antarctica, particularly the penguins - the most fascinating inhabitants of the icy continent.
