A humpback whale travels from Antarctica to the Colombian Pacific coast to give birth to its little calf, but is threatened by a whale hunting vessel that sails through the area and has managed to escape from international authorities. At the same time, Simón, Juana, Isabel and Lucas, accompanied by Aunt Abigaíl, arrive on Gorgona Island to embark on a submarine in the company of a famous scientist who studies the heart of whales. Little do the boys imagine what awaits them on board and the dangers they will have to face to escape the pursuit of pirate whalers who want to catch their prey at any cost.
