Skerry-18 (2011)

Evgeny Sormatov, a veteran of the special forces detachment, goes to a picturesque lake in Karelia. He carries with him the last letter of comrade Andrei Egorov, who died several years ago, and the Order of the Hero of Russia, which he was awarded posthumously. There, in a quiet corner on one of the skerries, in a deserted fishing village, Andrei's father and sister live.
