Baek XX follows the intense, divergent lives of twin brothers Baek Yi-soo and Baek Do-kyung. Yi-soo is a legendary HID agent, a specialist in covert operations and lethal combat, while his brother Do-kyung is a notorious figure who rose to the top of the criminal underworld as the leader of the Il-do Syndicate. Despite their shared blood, they exist in polar opposite worlds—until a sudden, violent conspiracy shatters their reality. After the tragic death of his brother, Yi-soo must abandon his life as a shadow operative and assume Do-kyung's identity to infiltrate the syndicate.

Stepping into the shoes of a mafia boss, Yi-soo utilizes his elite special forces training to navigate the treacherous politics of Seoul's gangs. This isn't just about survival; it is a cold-blooded mission to dismantle the organizations responsible for his brother's demise from the inside out. As "Mr. Baek," he faces constant scrutiny from both rivals and allies, leading to brutal confrontations where strategy is just as important as raw power.
