Somewhere between Kamchatka and Hokkaido is an uninhabited, largely inaccessible island in the middle of one of the coldest regions in Russia.

Their goal: the first descent of the volcano at the center of the island, but with temperatures of -20 degrees and unrelenting storms the expedition quickly becomes a dangerous odyssey.
