Nam Da-jung, an innocent college student, is unexpectedly invited to participate in a reality show called Liar Game, a psychological survival game where contestants deceive each other to win a grand prize of ₩10 billion (approximately US$9.3 million). Tempted by the opportunity to pay off her debts, Da-jung joins the game but is quickly swindled out of her initial funds. In desperation, she seeks assistance from Ha Woo-jin, a genius ex-con swindler and former psychology professor, to help her navigate and win the game.
