The Counselor visits a client, a prison inmate named Ruth who is on trial for murder. Ruth's son is a biker and a valued drug cartel member known as "the Green Hornet", recently arrested for speeding. The Counselor agrees to bail him out of jail. Malkina senses an opportunity to undermine the Counselor's upcoming deal and to profit for herself. She employs "the Wireman" to steal the drugs. He decapitates the biker, Ruth's recently released son, with a wire stretched across an empty desert road. Then the Wireman steals the truck containing the cocaine. Learning of the theft, Westray meets with the Counselor to notify him that the biker is dead and the cocaine stolen, bleakly intoning the Counselor's culpability. Westray says he is leaving town immediately and suggests the Counselor do the same. Westray explains that the cartel's ruthlessness extends to creating "snuff films" where murder victims are filmed having necrophilia performed on them on camera. The Counselor makes an urgent call to Laura, arranging to meet her in another state, where he will explain.
