When one half of the synchronized swimming duo the Aquadolls meets with an unfortunate end (murder by shark?), the Darling Mermaid Darlings get a chance to come out of retirement at a traveling water circus.
But the surviving Aquadoll may know a little too much about Lily's past.
Meanwhile, Ned, Chuck and Emerson go undercover to solve the murder.
