Out of the drug game and with new nightclubs, James St. Patrick is ready to leave “Ghost” behind and begin his new life with Angela. Just one problem: someone knows the truth about Vladimir, Drifty, Ruiz, and Lobos. Angela learns of a shocking discovery at work, and now must decide where to draw the line between love and honor. Without her husband by her side, Tasha reels from the death of Shawn while having an unsettling theory as to the identity of his killer.

With his drug organization unraveling, Tommy gains an advisor in his returned love, Holly, who enlists an old friend to solve a new problem.
Ghost is presented with a business opportunity that could take the clubs to the next level, but must outshine devious new rivals, all while looking over his shoulder for Lobos’s revenge. Tommy reunites with Tasha in a business scheme, while he also tries to keep a new drug contact under control and protect his reputation in the streets.

Tommy escapes to Chicago for a meeting with the suppliers that takes an unexpected turn. Dre and Cristobal set a plan in motion to get rid of Julio. And with Ghost released from prison, Jukebox and Kanan revisit their plan to kidnap Tariq, sending Ghost on a wild chase to save him.
As Ghost moves forward with his new business venture, the entire St. Patrick family is thrust into a new role in the public eye. Tasha seeks out Silver's help and their relationship deepens. When Tommy returns to New York, Dre talks himself into a promotion. And when Mak tells the whole prosecution team they're suspended, they start to form new alliances to find and take down Greg's real killer.
When Ghost sees that the location for his new business is in a gang-infested area, he has to re-team with Tommy to clean it up. As Tommy threatens war with the Jimenez, his organization starts to destabilize. Feeling the clock ticking, Mike makes a last ditch effort to pin Greg's murder on someone else as Angela tries to rally a team to take him down. Tommy learns the truth about his family.
