American workers inform soviet comrades about the impending catastrophe. But the air attack on the city has already begun, and the assault troops of the enemy capture one suburb of the city after the other. The Red Army is organizing the defense and reflects the attack of the enemy with gas-armed drones

Satire of the bourgeoisie and the West, anti-religious propaganda, agitation for a new lifestye, sees a young female revolutionary in a military helmet and miniskirt, ride a motorcycle through St. Petersburg

Typically of the heady days of early Soviet cinema, this is constructed according to the fast, sharp editing principles advocated by Eisenstein, complete with symbolic inserts; but in terms of subject matter, it's much less explicitly political than most movies emerging from Russia in the '20s. Chronicling a young sailor's descent into a murky, treacherous underworld of pimps and thieves, after having encountered a Louise Brooks lookalike at a fairground and missed his departing boat, it's a lively moral fable that delights in vivid visual effects and quirky characterisations. If the plot occasionally reveals gaping holes, and the tacked-on ending urging the clearance of the Leningrad slums seems to be rather gratuitous, there's enough going on to keep one attentive and amused.
