As NA Ok-boon scrutinizes around town and makes constant civil complaints, she is known as the ‘Goblin Granny’, and is a nightmare to the market merchants and the civil servants of the district office. Her biggest challenge after 20 years of filing complaints is Min-jae, a very principled entry level civil servant, who comes to stand up against the impetuous granny in her 70s with the eyes of a hawk for trouble. Granny NA is not only passionate about making civil complaints, but also learning English. When she finds out Min-jae studied abroad and is proficient in English, she clings to him for help.
