Lighter Than Love (2011)

Artificial light may have been one of mankind's greatest inventions, but it has also driven us apart from our families because it enables us to work longer and later hours. This drama tells three interconnected stories of people affected by light in different ways - A man forced to step away from work to take care of his injured mother in an apartment constantly lit by florescent billboards, the owner of a lighting shop whose products have suddenly stopped working, and a child who roams the streets stealing light bulbs.
