The Story
Park Chang-ho (Lee Jong-suk) is a mediocre lawyer, known for his low success rate and his habit of making big promises he never manages to keep. Nicknamed «Big Mouth» because of his talkative nature, he leads a modest life with his wife Ko Mi-ho (Im Yoon-ah), a determined nurse who stands by him despite his professional setbacks. His life is turned upside down when he accepts a case proposed by Choi Do-ha (Kim Joo-hun), the mayor of Gucheon.

The victim of a conspiracy, Chang-ho is accused of being «Big Mouse,» a mysterious con artist wanted for his criminal activities, and finds himself incarcerated in a particularly dangerous prison. To survive among the inmates and the powerful figures seeking to manipulate him, he must gradually assume the identity attributed to him. Meanwhile, Mi-ho conducts her own investigation to prove his innocence. Amid political corruption, secret organizations, and power struggles, the couple uncovers a conspiracy that goes far beyond a simple miscarriage of justice.
