As a young New York couple goes from college romance to marriage and the birth of their first child, the unexpected twists of their journey create reverberations that echo over continents and through lifetimes.

At Sydney’s National Dance Academy, a few talented youngsters are recruited for the excruciatingly tough course. It follows Tara Webster, a sheepfarmgirl who’s ambition is to be the next best ballerina. Jewish long line of doctors’ heir Samuel ‘Sammy’ and minor juvenile offender Christian are the outsiders but gradually fit in, making new kinds of friends. Star ballerina’s daughter Kat also introduces them in the circle of last-year brother Ethan, who already aspires a career as choreographer. Also Abigail, a smart young girl who’ll walk over dead bodies to reach the stars tries to sabotage everything and everyone.

Real-life mermaids, Sirena, Nixie and Lyla are part of a mermaid pod, which lives in the waters of Mako Island. As young members of the pod, it is their job to protect the Moon Pool and guard it from trespassers. But on the night of a full moon, the mischievous mermaid girls neglect their duties. Sixteen-year-old land-dweller Zac enters the Moon Pool and forms a special connection with Mako.

Zac is given a fish-like tail and amazing powers. The mermaid pod is forced to leave Mako, leaving behind the three mermaid girls, cast out of the pod. They know there’s only one way they will be allowed to rejoin the pod: They must get legs, venture onto land and take back Zac’s powers – or risk being outcasts forever.
