The Catbird Seat follows two intertwined narratives. One is set in the present, where Gillian Culkin, inconvenienced by demonstrators debating the presence of the Confederate flag at the South Carolina State House, begins to realize the flag’s presence represents important and entrenched issues of race and inequality. Meanwhile, she studies the 1857 diary of a dirt farmer who buys a slave at auction for a quick profit. In a subsequent journey, the man’s views of enslavement change.
