The movie "Honest Candidate" is a comedy about the three-term congressman "Joo Sang-sook" (played by Ra Mi-ran), who is the most likely to lie, but suddenly cannot lie one morning on the eve of the election, which leads to a lot of twists and turns. Ra Mi-ran, who became the "unbeatable comedy actor" with the box office success of "The Guy Inside Me" and "Police Girl" in 2019, returns through "Honest Candidate" as "Joo Sang-sook", who suddenly becomes the most honest politician in the world one day. It is expected that actress Ra Mi-ran will once again bring real laughter to the audience with her unique comedy acting skills.
