Many of us were taught in school that California was a "free state" that never had slavery. It was a lie. Gold Chains unearths stories about the enslavement of Black people, which was deliberately kept out of official histories of California. And we connect that dark past to today's calls for justice. Voices featured in this trailer include Tammerlin Drummond, Stacey L. Smith, Taylor Bythewood-Porter, Candice Francis and Marshal Arnwine.
