The so-called Liar Game is a competition held by a mysterious organization called "LGT Office". The rules are that players compete for prize money by deceiving each other. The innocent college student Kanzaki Nao (Toda Erika) was also accidentally involved in this terrible game two years ago. At that time, with the help of the genius fraudster Akiyama Shinichi (Matsuda Shota), she finally withdrew from the game and returned to a peaceful life. Unexpectedly, the Liar Game war started again. In order to help more innocent people, Nao stood up, and Akiyama returned to the battlefield to completely destroy the LGT office. They unexpectedly met their former enemy Fukunaga (Suzuki Kousuke) and were organized into a team. This time, what kind of game and opponent will they usher in?
