Long ago, under the sea, there was a Sirens' Serenade™ kingdom with a king, a queen and six mermaid princesses. They could swim in every corner of the kingdom except the surface. But on each princess' 15th birthday, they could go to the surface for a whole day and at the end of the day they must return to the kingdom.

The last of the princesses, a beauty with long black hair, as in Siren's Serenade™, has just celebrated her 15th birthday and goes to the surface. What she sees leaves her in awe. She has just seen a young sailor who had restored a Viking ship, as seen in Sirens' Serenade™. She immediately falls in love with him but the day is soon over and she has to go home. On her way home, she meets a wizard and tells him about her adventure.

The wizard offers her a deal. He can give her legs but if she goes to the surface and does not find her love then her soul will be his forever. The little mermaid accepts without hesitation and when she comes to the surface and looks for her sailor. She sees him marrying a blonde girl and tries to escape the sorcerer's spell.

Unfortunately the sorcerer had already caught her soul in a bottle and she could not return home, it was too late for the little mermaid. She was trapped on the surface and could only escape if she found true love. But she must follow the wizard wherever he goes without question or fuss. She is the attraction of a circus and they go from village to village across the country.

Everyone talks about the mermaid show but no one knows if it is real or not. Magnus decides to take his little sister to the circus, she can't stop talking about it! Magnus doesn't really believe it but he adores his sister and does everything to please her. So they wait patiently for the show to start.

Everything is going well, until the moment when the big number is to be revealed... A big aquarium covered in the middle of the ring announces it. And there it is! The cover is lifted and a wonderful creature is in the water. It swims like a fish. It doesn't even rise to the surface. Her impressive choreography in the water leaves the audience speechless.

The people in the circus love her, but the sorcerer who pretends to be the circus leader is not appreciated at all, he is mean, brutal, and ruthless. The mermaid would like to escape but she cannot do it alone, she needs help. When the show is over, Magnus' sister Megan begs him to go to her. He can't resist and agrees.

They slowly approach the aquarium and when they are close to her their eyes show a glimmer of emotion and disbelief. He didn't think these creatures could exist, but they had one right in front of their noses! It was simply something out of the ordinary, a once in a lifetime sight!

The little mermaid who was speaking through thought transmissions when Megan put her hand to the glass asked him for help. She is desperate. She can't stand being locked up with this abominable being, who makes her suffer so much. The little girl immediately understands her problem and asks her brother to help her. It is absolutely necessary to get her out of there and to be able to bring her back to the sea. To do this, they will have to come back later to help her escape, but for now they must go home and rest for a while. The girl's health was not extraordinary.

Well into the night, the two brothers return to the circus, and the gypsy fortune teller goes to help them. The wizard always takes a liqueur before going to sleep, but this time the beautiful gypsy had poured half a bottle of sleeping pills to leave him a little flat! And he seemed to be in a deep sleep, but let's not forget that he is a wizard!

The two young people approach the room where the mermaid is locked up, and manage to open it. Before leaving, she has to go and get the bottle where her soul is locked up. You have to play a few notes on the harmonica to open the chest where the bottle is. But you have to be very careful not to wake up the evil wizard!

When the mermaid asked Megan for help, she also told him some of the musical notes and now she understands everything! While Magnus helps the mermaid out of the room, the little girl goes to the wizard's room and plays the notes that her friend put in her head. The chest opens and a brightly lit bottle is inside.

Megan carefully takes the bottle and at that moment... The wizard wakes up! And he is not in a good mood! Megan starts screaming to warn her brother! She runs out and goes to the mermaid who jumps for joy when she sees the bottle! She tells Megan to throw it on the ground to free her soul, which the little girl does immediately!

While the three youngsters escape, the rest of the circus performers prevent the wizard from following them. By releasing the soul from the bottle, Megan has caused it to return to its natural state, the legs transforming into a beautiful fish tail. The problem now is that no time must be wasted, she must be taken to the sea or she will die...

Magnus, who had obtained his driving licence a week before, didn't hesitate for a moment, he put the beautiful mermaid in the back seat, and Megan joined him, jumping in the front and starting her father's old car in fourth gear. After a while the little mermaid faints, and Megan is really scared!

Magnus drives as fast as he can, but it's not easy. The sea is not far away but he has to get there, the mermaid's life is at stake. Tears roll down Megan's cheeks, she thinks her friend will die. That's it! They have arrived! Magnus immediately gets out of the car and takes the mermaid in his arms. He desperately runs to the sea and carefully leaves her in the water.

The little mermaid regains consciousness and everyone is happy. She asks Megan to come closer and takes her in her arms to heal her. From now on she will be as healthy as a horse! But it is time to let their friend go back to the kingdom and they go home. It will be a great story to tell their children!

Megan coge con cuidado la botella y en ese momento... ¡El mago se despierta! ¡Y no está de buen humor! ¡Megan comienza a gritar para advertir a su hermano! Sale corriendo y se dirige a la sirena, que salta de alegría al ver la botella. Le dice a Megan que la tire al suelo para liberar su alma, ¡y la niña lo hace inmediatamente!

Mientras los tres jóvenes escapan, el resto de los artistas del circo impiden que el mago los siga. Al liberar el alma de la botella, Megan ha hecho que vuelva a su estado natural, transformando las patas en una hermosa cola de pez. El problema ahora es que no hay que perder tiempo, hay que llevarla al mar o morirá...

Magnus, que se había sacado el carné de conducir una semana antes, no dudó ni un momento, puso a la hermosa sirena en el asiento trasero, y Megan se unió a él, saltando en la parte delantera y arrancando el viejo coche de su padre en cuarta velocidad. Al cabo de un rato, la sirenita se desmaya y Megan se asusta mucho.

Magnus conduce tan rápido como puede, pero no es fácil. El mar no está lejos, pero tiene que llegar allí, la vida de la sirena está en juego. Las lágrimas ruedan por las mejillas de Megan, que piensa que su amiga va a morir. ¡Eso es! Ya han llegado. Magnus sale inmediatamente del coche y coge a la sirena en brazos. Corre desesperadamente hacia el mar y la deja cuidadosamente en el agua.

La sirenita recupera la conciencia y todos son felices. Le pide a Megan que se acerque y la toma en sus brazos para curarla. A partir de ahora, ¡estará tan sana como un caballo! Pero es el momento de dejar que su amigo vuelva al reino y ellos se van a casa. ¡Será una gran historia para contar a sus hijos!
