A hundred dolphins live and play together in a region of water between Mont St. Michel and the English Channel, on the Contentin peninsula. Some impassioned observers are trying to get to know them better. Every summer, The Cotentin Cetacean Research Group, founded by Gerard Mauger, assembles a group of passionate naturalists to undertake an intensive study of this dolphin colony. A true human synergy of diverse backgrounds and talents has gathered around one of Europe’s most significant colonies. Now their sea quest can begin! This film is part of the ‘Seasons of the Bay’ Series.
