The Little Mermaid II: Return to the Sea continues the magical story of Ariel, now living on land as a human and married to Prince Eric. The film opens with the birth of their daughter, Melody, whose arrival brings joy but also awakens old dangers from the sea. Although Ariel has left her life as a mermaid behind, the ocean remains closely connected to her past and destiny.

Melody grows up curious and adventurous, constantly feeling drawn to the sea despite her parents’ efforts to keep her away from it. Ariel, remembering the threats she once faced under the ocean, becomes overprotective and hides the truth about Melody’s connection to the sea. This secrecy, however, creates distance between mother and daughter and makes Melody feel misunderstood and restricted.

The main danger in the story comes from Morgana, Ursula’s sister, who seeks revenge against King Triton and the entire royal family. Morgana discovers Melody’s identity and plans to use her to gain control of the trident, which holds immense power over the sea. By manipulating Melody’s curiosity and desire for freedom, Morgana succeeds in luring her into the ocean and temporarily turning her into a mermaid.

As Melody experiences life under the sea, she finally feels a sense of belonging and freedom. She makes new friends and begins to understand the beauty and complexity of the underwater world. However, she soon realizes that Morgana’s intentions are evil and that her own actions could bring great harm to both the sea and her family.

Meanwhile, Ariel must confront her fears and return to the ocean to save her daughter. In doing so, she realizes that love sometimes requires trust rather than control. With the help of old friends and her family, Ariel works together with Melody to stop Morgana and restore peace to the sea.

In the end, Melody makes a mature and heartfelt decision to remain human, choosing life on land while still respecting her connection to the sea. The film concludes with a powerful message about understanding between parents and children, the importance of trust, and the idea that true freedom comes from making one’s own choices while accepting responsibility.
