Lewis find out that there is a way for a mermaid to lose her powers and attempts to lure Charlotte to the Moon Pool. The plan backfire and it looks like all the girls may lose their powers.
In need of cash, Rikki decides to go and searching for a lost statue with a huge reward. But she lies to Emma and Cleo, which causes danger when Rikki is knocked out.
Charlotte's short-lived friendship with the other girls is over and she demands that out of loyalty to her, Lewis have no further contact with Rikki, Emma and most of all, Cleo.
Look ahead to the TV shows still set to premiere in the rest of 2020, including "Selena: The Series" and "The Stand."

My daughter (9) and I have watched it in the past and we're enjoying it again. For a series, this is really well put together. Yes, there are some cheesy lines, but the girls do a nice job. They can't help it that they had 2006 era phones! Just enough innocent teen romance to keep it interesting. I wish there were more than three seasons.
