Parents trying to prevent their son from seeing a girl they don't like go too far.

Based on Boris Akunin's novel 'Azazel' (English title 'The Winter Queen') set in Moscow in 1876. The novel started a long series quite popular in Russia. In 'Azazel' a young police officer - Erast Fandorin - investigates an odd suicide of some rich young man and finds a complex conspiracy, trying to take over most European countries - from Britain to Ottoman Empire - with the best intentions, of course.
