Tray Knight was just walking home from a friend's house one night when Chicago's finest stopped him. Maybe it was the hoodie, maybe it was his race, either way, Tray wound up dead.

The public's up in arms but a DA up for re-election, a news caster with her eye on National, and a station house full of racist cops could care less.

And that's when one of the downtrodden steps up. Trained by the US government in Iraq, Afghanistan, and God knows where else, this urban vigilante is ready, willing and able to take the law into his own hands. Justice is coming to Chicago – and his name is Black Walnut!
