In 1970s South Korea, follow two men on opposite sides of power — one driven by ambition, the other by justice. As their worlds collide, greed, loyalty, and survival intertwine in a battle that will shape a nation.
Season 1 follows Baek Kitae, an ambitious KCIA agent who's living a double life. Driven by his thirst for power, Kitae works as an agent by day and a smuggler by night. Smart, suave, cunning and capable, Kitae rapidly moves up the ranks after using his smuggling operation to consolidate power, protect his brother, and generate vast sums of money for the agency. Seemingly unstoppable, only one thing stands in his way - a tenacious prosecutor who can't be reasoned with, bought or bribed. With everything at stake for both men, follow the duo as they look to take each other down.
Nine years after Season 1, Baek Kitae stands at the height of his power, while Jang Geonyoung is preparing to strike back. Meanwhile, Baek Kihyun is pursuing a path to a different kind of power than his brother. Their ambitions run rampant, creating an irreversible rift that threatens to upend everything.
