Cocoon - A Aventura dos Corais Perdidos

A group of delightful and very human people meet up with some very bizarre and not-so-human beings, who are visitors from a distant galaxy. They have come to Earth on a rescue mission to retrieve a secret which has laid hidden on the ocean floor for thousands of years. They share a more wondrous adventure of love and friendship that they could ever have imagined. (20th Century Fox Home Entertainment)
