Outcasts

S1 E1: Young mermaids of the Mako Island pod, Lyla, Nixie and Sirena have the task of keeping trespassers off the magical island. Nixie and Sirena, bored with their job, decide to have fun with a couple of land dwellers, Zac and Cam, who are fishing off the island, and fail to stop them camping overnight on Mako. During the night, as the full moon rises, the mermaids are less than enthused by their duty - they want to join the pod out at sea for the Full Moon celebrations. However, as the moon approaches its zenith the three mermaids enter the sacred Moon Pool to bathe in the moon's powers. During the night, Zac accidentally discovers a secret chamber in the rocky face of Mako's extinct volcano. While he explores inside he unlocks a hidden entrance to the Moon Pool. Zac falls into the bubbling waters, shocking the young mermaids. Luckily he is unconscious. The next morning Zac wakes up on the beach with no memory of what happened after he entered the chamber, and the boys decide to leave the island. But when Zac gets home he discovers he has special powers, and that contact with water transforms him into a merman! The Mermaid Council rules Zac a great threat to the pod, and declares Mako unsafe. As punishment, Sirena, Lyla and Nixie are banished when their pod leaves the island. Just before Aquata leaves Mako, she gives her younger sister, Sirena, her Moon Ring - she may need it. The young mermaids must find a way to fix what they've done, or be outcasts forever.
