Sandstorm 2004 on netflix

For twelve days and nights, He Tian Ying and his wife have been trapped in their home during a massive sandstorm covering a large area of China. His wife is running out of life-sustaining medicine, their young daughter is missing in the storm, electricity and phone communication have been cut off, and their food and water are running out. As He Tianying cares for his dying wife, in this isolation and confinement, his conscience starts to emerge. As a policeman, he has been involved in the vicious persecution of common Chinese citizens who follow the spiritual practice of Falun Gong. In a series of flashbacks, he painfully recalls one particular Falun Gong practitioner whom he had been attempting to force to renounce her beliefs.
