The story of Dyesebel begins when an amnesiac mermaid-turned-human named Lucia (Jean Garcia) fell in love with a human. They got married and had a beautiful baby, but instead of human baby she delivered a mermaid. The child is called "Dyesebel" (Marian Rivera). Although surprised by their daughter's strange form, Lucia and her husband Tino (Wendell Ramos) promise to love their child no matter what.
