Various contestants take part in a game show with a prize of 10 billion won. The contestants who can cheat the otehrs wins the prize. Contestants include genius swindler Cha Woo-Jin (Lee Sang-Yoon) and naive college student Nam Da-Jung (Kim So-Eun).
Kanzaki Nao is an honest college student who receives a hundred million yen one day, along with a card saying she has been chosen to take part in the "Liar Game". The aim of the game is to trick the other players out of their hundred million dollars. Really cool and thought provoking.
