In a shabby Soviet-era apartment stairwell, a man in glasses and a grey knit sweater stands at a smashed-open wall niche stuffed with electrical wiring, poking at it with a screwdriver and arguing over his shoulder. A curly-haired man in a leather jacket keeps tramping up and down the concrete stairs to keep the argument going, and at the end crouches at the bottom of the wall by the apartment door inspecting something there.
