The series opens with Marin City, a town the federal government built in 1942 beside the Marinship shipyard on a Sausalito mudflat to house war workers, including Black families from the South. The yard closed but the town stayed, and so did the question of who belongs in its schools. The episode previews the wartime migration and the doors it opened for Black Southerners and women and shut on Japanese Americans.
Counts of wartime migrants differ by definition, though it is well established as the largest internal movement in U.S. history. The claim that Sausalito was among the first districts to integrate is a family account still to be checked against the record.
