A comedic blend of murder, mystery and marijuana. Trying to escape the infamy of a serial killer father, Trent Modine and his goof-ball stepbrother Joey, both seeking a new start, find refuge in the small town of Mooseheart.
Told from the perspective of Henry 'Little Onion' Shackleford, a newly freed teenager who joins abolitionist John Brown on a holy crusade to end slavery. Onion encounters Frederick Douglass and Harriet Tubman, and he finds himself as a part of the famous 1859 raid at Harpers Ferry.
