When the headquarters of the British secret service agency, known as the Kingsman, are destroyed by a ruthless criminal cartel called The Golden Circle, the survivors of the attack discover that they're not alone in their quest to uphold global security. The incident leads them to their American counterpart, an allied secret organization called Statesman, which operates under the guise of a bourbon whiskey distillery in Kentucky. The two agencies form an uneasy partnership to tackle the global threat posed by the Golden Circle's enigmatic and malevolent leader.

As the Kingsman and Statesman agents collaborate, they face a series of perilous challenges that test their strength, intelligence, and resourcefulness. With the world held hostage by the Golden Circle's devious scheme, they must race against the clock to thwart the cartel's master plan, which involves the widespread distribution of a lethal drug. Each agency brings its unique set of skills to the table, with the Kingsman's sharp sophistication meeting the rugged American bravado of the Statesman. The agents must learn to work together and trust one another if they hope to save the world from catastrophic consequences.
