At the end of the last season, Vic was on the verge of despair. Because Shane needed the help of the Armenian gang, he got rid of all the inside information of their robbery of the gang's money transporter, which made Vic's family hunted by the Armenian gang. He also faced the review of the final committee and his position was lost. But he found the last straw. The invasion of the Mexican gang brought Vic and Aceveda together again, and accidentally obtained a box of inside information about senior officials in the Farmington area collected by Pezuela, a company controlled by the Mexican gang. In the new season, Vic and the Mexican gang Pezuela company are the main focus; how to deal with the relationship with Shane, the Armenian gang has not been resolved; Vic returns to the police force, who will be the team members? I wonder if the prosecutor played by the old enemy Forest Whitaker will return this season? Will Dutch and Danielle get along? And so on.
