After the October Revolution a small island with orthodox monastery is passed to Finland. The Finn Army places there an executive staff of coast artillery. The Soviet command sends to the island a former priest's son and now soviet commissar Maxim Proshin. He is to wriggle way into the island as a novice and murder one of the high rank Finnish military man. Maxim will have to pass a way of penance and mental rebirth to find himself and achieve self actualization.
