In the Dark of the Valley

A Southern California mother discovers that the Santa Susana Field Lab, the site of one of the largest nuclear accidents in U.S. history, is located only 7 miles from her home. Concealed from the public eye for 20 years and never fully cleaned up, she grapples with the idea that the site may be responsible for exposing her daughter and community to cancer-causing radioactive waste. The feature documentary, directed by Nicholas Mihm, airs Sunday, November 14th at 10 p.m. ET on MSNBC.
