A vanished submarine prompts a rescue operation that leads to the Loch Ness monster. Having escaped the Loch, the creature unleashes decades of pent-up aggression on those it encounters.

Following a brawl, Captain Ignat, who is traumatised by the death of his daughter, is ordered together with a regular soldier to find a deserter and bring him back via Moscow to stand before a military court. Although they locate the young soldier, their journey across the wintry moloch that is Moscow is slow and tortuous. Before long, the unlikely trio find themselves drawn into a chaotic maelstrom of violence, corruption, criminality, degradation and squalidness. In the face of the monstrous malaise and everyday horror of life in Russia, the gradual breakdown of the film’s anti-hero becomes a metaphor for Russian society.
