Errol Morris confronts one of the darkest chapters in recent American history: family separations. Based on NBC Political and National Correspondent Jacob Soboroff’s book, Morris merges explosive interviews with whistleblowing officials and artful narrative vignettes tracing one migrant family’s plight. Together, they reveal that the cruelty at the heart of this policy was its very purpose. Against this backdrop, with hundreds of families still separated years later, audiences can begin to grasp the US government’s role in this unthinkable horror and be warned that we are on the verge of allowing it to happen again.
