In “One Dollar Lawyer”, ‘Nam Goong Min’ takes on the role of 'Chun Ji Hoon'. Unlike ordinary lawyers, ‘Cheon Ji Hoon’ is like a eccentric lawyer. However he is expected to present a heart-warming humanism with the secretary (Park Jin Woo) and ‘Baek Ma Ri’ (Kim Ji Eun) by paying attention to litigation that does not make money and cases where there is no chance of winning, and sincerely resolves the injustice suffered by the underprivileged who are not protected by the law.
