Police Lieutenant Colonel Alexandra Kushnir was transferred from the Department of Internal Affairs of a large city to a small seaside town and appointed head of the criminal investigation department.

The Old Man, the Bald Man, Lenin and 148 other nicknames are pseudonyms of the hereditary nobleman Vladimir Ilyich Ulyanov.

He is a retarded infant, a thin, red–haired teenager, a young student, a provincial social Democrat, a young lawyer who traded his career for exile to Siberia.

He is Lenin, the preacher of the armed struggle against autocracy, the man who organized the supply of weapons and ammunition to Russia, whose slogan is "Fight together, go separately" – it does not matter with whom: with dark people or with the general staffs of the Japanese and German armies. An incredibly able-bodied, passionate orthodox Marxist who paved the way to power with his pragmatism.
