Years have passed since Emma, Rikki, and Cleo have last seen each other. They have moved on from the time they had together in the Gold Coast to pursue careers and families. When each of their daughters is 16, something-- perhaps magic-- brings them all back to the town in which they grew up. Emma, Rikki, and Cleo are now forced to face each other again and work through the past that resulted in their separation for the sake of their girls while also keeping their biggest secret from their own children.

H2O: Just Add Water Sequel! Hope you all enjoy! Each part is a little short and kinda vague but it's just my writing style I'm working on improving it!

Taking place one month after the season 3 finale, Emma returns to the Gold Coast after 9 months of traveling the world. Excited to reunite with her BFFs, Rikki and Cleo, she soon sees they no longer wear their lockets as well as have met a new mermaid: Bella, who they've befriended. Tension arise between the girls as mixed emotions flow. When Rikki and Cleo become trapped in a dangerous situation, Emma and Bella will be forced to put their differences aside and help their friends.

It could definitely be said that Cleo, Rikki, Emma and Bella have overcome the storm. Their friendship is now stronger and they've done so many things together. But just as summertime is in full swing, an unexpected cloud pops up. Charlotte returns to the coast. After having left out of shame from her defeat, Cleo thought she would be free from Charlotte for good. Charlotte promises that she has turned over a new leaf and is simply visiting the town before going off to college in the fall. But of course, Charlotte actually wants revenge, at any cost. Having been researching Mako Island in the year she's been gone, she is determined to regain her mermaid powers. When she discovers the moon pool is damaged (see season 3 finale), Charlotte makes an alliance with an old foe of the mermaids to regain her tail and defeat them.
