Dyesebel (Charlene Gonzales) is unique among the merfolk for she is the only mermaid born of human parents from the surface world. A mermaid from birth, she is shunned by the superstitious due to her physical form. After her father is killed by an angry, superstitious mob, Dyesebel is taken to the ocean by her mother where she is sent into exile since her chances for survival are greater there than on land. The young girl-mermaid is found by Banak (Gloria Diaz) who adopts her and takes her to their kingdom where she is welcomed into their community. Years later, a jealous mermaid named Dyangga (Maritoni Fernandez) makes Dyesebel's life miserable among the denizens of the sea, which leads Dyesebel to try returning to the surface world. She meets a kind, handsome young man named Fredo (Matthew Mendoza) who falls in love with her and protects her, but she is kidnapped by Fredo's jealous former girlfriend's new boyfriend and displayed at the circus. She is subsequently rescued by Fredo and is brought back to the ocean. Fredo and Dyesebel later got married.
