Ethan Hawke, Daveed Diggs and Joshua Caleb Johnson star in a humorous, dramatic and historical tapestry of Antebellum America based on the award-winning novel by author James McBride. Told from the point of view of Onion, a newly freed teenager who joins abolitionist John Brown on a holy crusade to end slavery and finds himself part of the famous 1859 raid at Harpers Ferry, the limited-event series is an adventure equal parts absurd and tragic, spotlighting the ever-changing racial, religious and gender roles that make up the American identity.
