点滅の朝 (1992)

Two young rubbish cleaners are working in a deserted high-rise before dawn. A middle-aged businessman walks past them, deliberately cracks open a bottle of alcohol and walks away. They stare at him with dark eyes, still feeling the way they did a month ago when they found the dead body of a woman. As one of them picks up a bottle of wine, the other finds a plastic bag in the pile of rubbish, which seems to contain a cat.
