Overview
A lawyer with a ten-percent winning rate is caught up in a murder case and becomes the notorious and genius con artist, Big Mouse, overnight. In order to survive and protect his family, he tries to reveal the true colors of the privileged people involved in a huge conspiracy.
Big Mouth leans into the aesthetics of film noir while navigating the ruthless mechanics of institutional greed. It centers on a lawyer dragged into a shadow world where survival demands a sudden, calculated transformation. The narrative relies on a steady drip of mysterious messages and the threat of an unseen killer, forcing the protagonist to dismantle a protected class of elites from the inside.
Lee Jong-suk anchors this high-stakes investigation as the line between innocent victim and criminal mastermind blurs. The show finds its momentum in the friction between personal desperation and the cold logic of a secret organization. Rather than leaning on simple heroics, the story focuses on the messy, complex fallout of a murder investigation where the truth is consistently weaponized.
