Buck Calhoun, Ph.D. Professor Emeritus, Administration of Justice Department, lives on a well-maintained boat, the C-Breeze. Prior to retirement, he became licensed as a Private Investigator. After retirement, he created Unit-302, a select group of investigator associates. On this occasion, Buck receives a call from the father of a veteran-killer through an Associate. The father was a Korean War veteran. Now, he seeks to determine why his son chose to end his life in such a tragic manner, murder and suicide. Buck's sympathies for combat veterans, however, were not the decisive factors in his decision to accept the case. Rather it met his criteria for service. The episode was officially closed. The purpose now was not to re-open the case, or seek any form of compensation. The father was not seeking who to blame or someone to charge with incompetence or even to question the philosophy or quality of therapies used to treat PTSD veterans. He wasn't interested in litigation, revenge, or punishment. He sought facts, plausible explanations, and closure. He wanted truth, not opinion or speculation. Buck calls on his Associates who uncover disturbing evidence that call for careful analysis and evaluation. For this, he in turn calls on his old friend, retired university teacher, Tweedy Flynch, once again enlisting his help -- a role Tweedy accepts as a friend.
