Aquamarine conveys to the girls that she must prove to her father that love exists or she’ll be forced to marry a merman that she’s never met.Aquamarine seamlessly transforms into a human girl during the day and can remain that way, as long as she doesn’t get wet. At night, she reverts back to her mermaid form.
When Aquamarine meets Raymond (Jake McDorman), he rejects her advances. Hailey and Claire see how devastated Aquamarine is and makes it their mission for Raymond to fall in love with her. But their plans are thwarted by mean girl Cecilia (Arielle Kebbel), who also has a crush on Raymond and is constantly standing in the girl’s way.
At the street fair, Raymond spends some time with Aquamarine and asks her to go to The Last Splash party with him. Aquamarine is flattered, but leaves abruptly, not giving him an answer because it’s almost sunset and her legs will transform into a tail. Claire and Hailey find a water tower for Aquamarine to spend the night in, excited for Aquamarine’s date with Raymond the following night.

But Cecilia has other plans. She goes to Raymond and tells him, that Aquamarine has a boyfriend in another town and invites Cecilia to the party instead. Hailey and Claire find Raymond and tell him that Cecilia is lying about Aquamarine, so he gets back together with Aquamarine.
Aquamarine and Raymond dance at the party and they become incredibly close. Unfortunately, Aquamarine can’t stay for long, since it’s almost sunset and she’ll transform back into a mermaid. She flees the party, leaving Raymond baffled about her abrupt departures.
Cecilia follows Aquamarine to the water tower and discovers that she’s a mermaid. Cecilia seeks out the press to expose Aquamarine and her secret to the world. Aquamarine, however, is one step ahead of her, the handyman Leonard helps Aquamarine and she grants him a wish.

Cecilia is humiliated when she takes the press to the water tower and Aquamarine isn’t there. She swears that Aquamarine is a mermaid and will prove it.
The following day, Aquamarine asks Raymond if he loves her. He tells her that he likes her, but he doesn’t her. She’s devastated by his answer, and as luck would have it, Cecilia is nearby. She pushes Aquamarine into the sea and she turns into a mermaid. It doesn’t take long, for Aquamarine’s father to call her home with a great big storm. Hailey and Claire jump into the water, not wanting Aquamarine to leave. They find her on a buoy, clearly defying her father’s orders to return home. Aquamarine tells Claire and Hailey that she had learned that love exists from their friendship and that she’s learned so much from them. This answer, is enough to prove to Aquamarine’s father, that love in fact exists.
As a form of gratitude, Aquamarine hands Hailey and Claire a starfish, so they could make a wish. Hailey changes her mind about using her wish to not move to Australia, knowing how hard her mother worked to get the new job. So instead, Claire, Hailey, and Aquamarine promise to always visit each other and to love one another forever. Aquamarine swims up to Raymond, in her mermaid form and he asks her when she’ll surface again. She tells him that she has to talk to her father about a few things and then she’ll return to him.
And finally, Aquamarine and Raymond share their happily ever after with a tender kiss.
