"Le Grand Chef 2" begins with the Korean president visiting the Japanese Prime Minister and becoming involved in a heated debate over the origins of kimchi. The Japanese Prime Minister makes the bold claim that kimchi is an original Japanese dish which sets off the Korean president. Upon the Korean's president return home he sets upon a globalization plan for kimchi, which includes a nationwide "Kimchi Contest". Then, a lady named Jang-eun (Kim Jung-Eun) and her step-brother Sung-Chan (Jin Goo) compete in the Kimchi dish contest, with both siblings using their mother's kimchi recipe.
