Luces en el mar (Elena Sirena, 4)

Elena has a very clear goal: to compete and reach the top as a synchronized swimmer! And the most surprising thing of all is... she can become a mermaid! But lately she's been a little worried: there's tension at home because she can't be honest with her father, she doesn't quite fit in with her new duet partner, and on top of that, it seems her friend Eva wants to go her own way, without the E-girls... Everything is upside down, and having Lucas away makes it even harder. Will she be able to make things go back to normal?
