In the wake of a disastrous mission overseas, Navy SEAL Commander James Reece returns home with conflicting memories of the op and questions about his own culpability.

Reece is drawn deeper into a complex conspiracy and puts a new name on his list. Meanwhile, Secretary of Defense Lorraine Hartley announces a drastic policy overhaul to help Special Operators. And Katie discovers the truth of what's going on in Reece's head.

Reece travels to San Francisco to seek answers on a drug that may have started this all. Katie attempts to turn Mike Tedesco in an effort to blow up Capstone's plans for Nubellum. Tony and his team stick close to Horn, hoping to intercept Reece before he kills his next target.
