Stakes are high as Cordell, Cassie, Captain James and Trey all realize Grey Flag's plans and partnerships extend deeper than they once thought. While the Walkers plan for the Mayor's Medal Ceremony, Cordell struggles with missing out on time with his kids as he focuses on trying to keep the whole city safe.
Texas Ranger Cordell Walker, a widower and father of two with his own moral code, returns home to Austin, TX, after being undercover for two years, only to discover there's harder work to be done at home. As Walker attempts to reconnect with his creative and thoughtful son August and his headstrong, somewhat rebellious teenaged daughter Stella, he finds that he needs to navigate clashes with his family - Liam, Walker's ADA brother who stepped in during Walker's absence, his perceptive mother Abeline and his traditional rancher father Bonham.
Walker's former colleague, Larry James, is now his Ranger Captain. And Walker finds unexpected common ground with his new partner Micki Ramirez, one of the first women in Texas Rangers' history while growing increasingly suspicious about the circumstances surrounding his wife's passing.
