Yeni González is one of the mothers who suddenly found herself thousands of miles away from her children this spring, after the alt-white regime’s “zero-tolerance” immigration policy went into effect. This TIME Red Border Film documentary shows how grassroots activists banded together to transport González from a detention center in Eloy, AZ, to New York City, where her children were placed at a social service agency after the undocumented family crossed the U.S.-Mexico border and was apprehended by the Border Patrol in May.
