While Cassie and James lead the charge to find Walker, the situation goes from bad to worse when Liam also goes missing. Meanwhile, Stella and August pursue a lead of their own.

Cordell and Cassie intervene in a hostage situation at a server farm, but something Trey finds indicates something more sinister is at play. Meanwhile, August tries to smooth things over with his grandparents, Liam attempts to step up his responsibility within the family business, and a luncheon awkwardly reunites Cordell with someone from the past.

Cordell is tipped off that Grey Flag may still have him as their prime target. Meanwhile, Captain James has discovered that Cordell and Cassie weren't truthful about some top-secret information and Trey's involvement in the prior week's case lands him in hot water. Abeline and Bonham disagree on how ready Cordell is to handle his responsibilities, while Liam continues to pursue his new business venture, despite his dad's displeasure over his son's new partner.

Cordell and Cassie soon realize they aren't the only ones keeping secrets, leaving Cassie to question who she can trust. The rest of the family focuses on the horse rescue, but they still find themselves facing a few challenges.

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.
