It is 1965, and Cora, a young, hearing impaired woman, buys a one-way ticket to the island of St. Thomas, where she discovers four dolphins held in captivity as part of an experiment led by the obsessive Dr. Blum. Drawn by a strong connection to the dolphins, Cora falls in with the scientists and discovers her need to protect the animals. Recognizing Cora's knack for communication, Blum uses her for what will turn into one of the most fascinating experiments in modern science: an attempt to teach the dolphins human language by creating a home in which she and a dolphin can live together.
