Avalanche by Morteza Farshbaf (Iran, 2014, 90 min.).  The remarkable Fatemeh Motamed-Arya gives a nuanced, tour-de-force performance as elder care nurse Homa, who is charged with caring for an old woman during a snowstorm that shuts down the city.  The strain of her responsibilities and the claustrophobic situation bring on insomnia and a personal crisis. 

In Farsi with English subtitles. Presented on DCP.
