Her mother is Calissa, the Queen of Oceana, but Calissa's evil sister Eris has stolen the throne. Along with her dolphin friend Zuma, Merliah sets off on an undersea adventure to rescue her mother and discover her true destiny. She must get three items to succeed: the celestial comb, a dreamfish and Eris' protective necklace.
