Ocean, mermaids, and the beautiful sky. That is all you need for one simple and adorable lakorn. Meenanoot (Mew) and her older sister, Masaya (Mam Vichuda) are of course, mermaids. They're beautiful, innocent, and intelligent. On top of all that, they are curious about the human world. Their curiosity leads them to meet the father and son, Ajarn Thara (Krerk) and Chonatee (Pop), respectively. Ajarn Thara, Chonatee's father is a marine biologist/professor and Chon is a student from the University of Marine Science, which is situated along the ocean shoreline. Soon, both father and son begin to believe that mermaids are real and to prove that, Ajarn Thara buries himself in tons of research. What will they think when the woman beside them are mermaids? Will the research project carry on? Will their love grow and prosper?
