After living a lonely life in Europe for many years, Violetta (Martina Stoessel) returns home to Buenos Aires with her father, German (Diego Ramos). The arrival refreshes many questions the teen has about her mother, whose untimely death many years ago caused a rift in the family that German hoped to put behind him by heading overseas, but German refuses to talk to his daughter about his late wife. Fortunately for Violetta, her aunt, Angie (Clara Alonso), re-enters her life and becomes her mentor, giving her piano lessons at the prestigious music school Studio 21. There Violetta discovers her untapped talent for singing as well, a skill that she inherited from her mother but that her father adamantly discourages. Meanwhile, being among peers at Studio 21 raises a whole new set of issues for the sheltered teen, and she must navigate the ups and downs of friendships, crushes, and the mixed emotions of growing up.
