When teenagers Cleo (Phoebe Tonkin), Emma (Claire Holt) and Rikki (Cariba Heine) wander into a mystical pool while stranded on an isolated island during a full moon, they turn into mermaids with magical powers in this fantasy television series from Australia. With a little help from their friend Lewis (Angus McLaren), the girls struggle to keep their secret safe -- which means staying far away from the water.

Rikki fears Ryan's explorations on Mako Island will uncover their secrets but Cleo and Bella discount her concern. She almost goes too far trying to stop Ryan from discovering the crystals in the Moon Pool.

Sophie uses Bella's idea for a fundraising concert and presents it as her own to Rikki to gain publicity for the cafe. Cleo's caught in the crossfire with Kim when Samantha moves in and puts her stamp on the Sertori home.
