We start off meeting a substitute teacher who is quickly introduced to the awful world of cyberbullying.  This makes him go postal with a bunch of cell phones and a wood chipper. But who is he? We are then thrust right into the casino life that the Byrdes and Ruth are running full boar, looking for creative ways to launder the cartel money.  We also get a glimpse into the human side of Helen, with her daughter Erin reluctantly joining the Ozark family. Charlotte has become the family business secretary, and Jonah is on drone patrol. Finally, we meet Navaro, the head of the cartel, via cell phone.
