In 1850s Kansas, fate found young, orphaned slave Henry Shackleford (Joshua Caleb Johnson) falling under the guardianship of zealous abolitionist John Brown (Ethan Hawke), who mistook him for a girl and dressed him accordingly. His unlikely odyssey, which would bring him encounters with Frederick Douglass (Daveed Diggs) and Harriet Tubman (Zainab Jah), is followed in Showtime’s flavorful take on the James McBride novel. Beau Knapp, Nick Eversman, Ellar Coltrane co-star. 5 1/2 hrs on discs. Widescreen; Soundtrack: English.
