THE GREAT MOTHER 9 p.m. on Starz. This documentary tells the story of Nora Sandigo, a Miami woman who serves as the guardian to more than 1,000 children who were born in the United States to undocumented immigrants. Sandigo, who fled Nicaragua as a teenager, moved to Florida in the late 1980s, where she started working for an organization that helped immigrants with documentation. After President Trump took office, many parents in the immigrant community started to give Sandigo power of attorney, so that she could make decisions for their United States-born children, should they be deported. This designation protects the children in Sandigo’s care from entering the foster care system, keeping them from being legally separated from their parents. When Sandigo is not making grocery runs, contacting lawyers or trying to find beds for the hundreds of people she looks after, she makes trips to Washington to meet with lawmakers to discuss immigration policy. The filmmakers Dave LaMattina and Chad Walker followed Sandigo over two years during and following the 2016 election for this documentary .
