Whoever said that “the only constant thing in the world is change” must not have known love of the eternal kind. “My Eternal” narrates the poignant story of love and revenge that spans three family generations. All of which were witnessed by the hill that overlooks the wineries of the Montenegro and Alcantara families. And based on what it has seen, the hill could attest that time and tribulations can transform anything except eternal love. Marco, the heir to the Montenegro’s winery falls in love with their worker’s daughter Emily. His mother Margaret feels strongly against this relationship and makes sure they don’t end up together. She puts Emily in prison and her grandchild up for adoption while Marco builds a family with another woman. Emily vows to return for revenge and will do whatever it takes to be rich like the Montenegros. Meanwhile, Emily and Marco’s son Daniel grows up in the vineyard beside the Montenegro’s not knowing his real identity. He comes to know a pure and eternal kind of love with Katerina. Unfortunately, she is the girl bound to marry Marco’s legitimate son Nathan. Filled with hurt when Katerina marries Nathan, Daniel is forced to leave. Like his mother Emily, Daniel vows to seek revenge on those who caused him pain. Mother and son are reunited with the purpose of exacting revenge on the Montenegros, both unaware of the real tie that binds them. More complications arise when Daniel discovers the truth about where he came from.
