This is a tale of a little girl named Ariel (Jodi Benson) and her sisters. The city of Atlantica is banned from music after a tragic death, and she stumbles across something that will change her life forever. The bad thing is that King Triton (Jim Cummings) finds out, and several underwater friends get put into jail. After finding out that they were put in jail, she leaves the city and family she so loves so she can be happy and sing the music she loves even more. While on their journey away from the city, her friend Sebastian (Samuel E. Wright) helps her find the key to everyone’s joy. The only thing is can they get the king to be happy and love music the same way they do?
