Agathe loves tractors, and rock! She works in the family farm machinery garage with her father and older brother. When she finds out about an upcoming Airguitar competition, she decides to enter, but her brother doesn't see it that way.

Agathe works at her family's repair shop, blasting heavy metal as she fixes machines. Dreaming of showing her love for music, she enters an air guitar contest as 'Attila', named after her donkey—ignoring her brother's scolding to grow up. Lady Attila is a lively, cheering tale of chasing dreams. With her grandmother and a hint of magic behind her, Agathe's journey to the stage is bold and joyful. The moment her overalls turn into a dazzling costume and her garage energy erupts on stage is electrifying. When silence falls, the film ends gently on the siblings' tender bond. (Lee Yoochae)
