In the tense political climate of the 1960s, the U.S. President has negotiated a controversial nuclear disarmament treaty with the Soviet Union, sparking widespread public and political unrest. Among those vehemently opposed to the treaty is General James Mattoon Scott, a high-ranking and influential military official who believes the President's actions will lead to the nation's downfall. Marine Corps Colonel Jiggs Casey, initially oblivious to any imminent threat, gradually uncovers hints that there may be a sinister plot brewing within the highest ranks of the military. Growing more suspicious by the day, Casey stumbles upon cryptic communications and clandestine meetings that suggest a possible coup d'état is being orchestrated by those sworn to protect the nation.

With time running out, Colonel Casey risks his career and personal safety to alert the President and his inner circle of the looming danger. Navigating a perilous path filled with doubt and mistrust, Casey must gather concrete evidence while contending with Scott's loyal followers, who are deeply embedded in powerful positions. As tensions escalate, every decision becomes a matter of national security and loyalty, leading Casey into a race against time to avert a catastrophe that could alter the very fabric of democracy. The future of American governance hangs precariously in the balance, leaving everyone to question whom they can ultimately trust in a world where power and betrayal go hand in hand.
