The Little Mermaid: Ariel's Beginning

Ariel, a spirited and determined young mermaid, lives under a strict routine with her father, King Triton, after he bans music from the underwater kingdom of Atlantica following his beloved wife's death. Ariel befriends Flounder and discovers an underground music club, where she sings about her mother's memory and is accepted as a member. She returns to the palace, but her father's anger and ban on music lead her to run away with her friends, ultimately bringing music back to the kingdom through her father's emotional reunion with his daughter.
