Spunky fourteen-year-old Aiko Cassidy is a manga comic creator, hiding behind the ultra-superheroine of her creation. While Gadget Girl swoops in to save the day and relies on her strength and precision in the pages of Aiko's comic books, Aiko herself wishes she could conceal herself from the whispers and stares from kids about her cerebral palsy. Aiko grapples with her desire to meet her Japanese indigo-farming father and living with her eccentric sculptor mother. The mother and daughter duo end up travelling to Paris where Aiko is uncomfortable with all the attention she and her mom receive. Soon, she begins to deftly navigate the challenges in her life, as well as the makings of a potential love interest. Gadget Girl is heart-warming story of a young girl searching for her identity and finds it in herself and the people with whom she connects with from home and across the ocean.
