John encounters a gangster named Jimmy whom he is forced to kill. A Jamaican gangster named Nesta arrives and is subdued by John, who asks about Screwface. Nesta gives information but tells him to go after Screwface alone and jumps out the window to his death. The next day, John discovers a strange symbol engraved on a carpet, and with the help of Jamaican voodoo and gang expert Leslie Davalos, a detective for the Chicago Police Department, he learns that it is an African black magic ideogram symbolizing blood that is used to mark their crimes. John decides to come out of retirement to join Max in a battle against Screwface. Max's 13-year-old nephew died in a crack house some time ago, and that's the biggest reason why Max hates drug dealers.
