Woo-seok is a tax attorney whose practice drastically shifts when he encounters a shocking incident—the abduction of his friend’s son who gets tortured by the government in the name of national security, falsely accused of being a sympathizer of North Korea. Inspired by a true story, The Attorney examines the period in which the government’s injustice and brutality were justified and many innocent individuals were victims of merciless violence. Song Kang-ho, who portrays Woo-seok, conscientiously weaves the elements of the character into a radicalized entity motivated by empathy and infuriated by injustice.
