During the Exodus, one of the most famous miracles of the Old Testament took place. More than 3000 years have passed since Moses led two million Israelites across the Red Sea and out of the bondage of Egypt. Christians, Jews, and Muslims throughout the world still embrace the accounts of this remarkable event. It is an epic that so fascinated Hollywood director Cecil B. DeMille that he made THE TEN COMMANDMENTS, twice. Now THE EXODUS REVEALED follows the footsteps of the children of Israel in an unforgettable journey of discovery. A journey that reveals physical evidence for the Exodus including: the remains of 3800 year old Hebrew settlements in Egypt's Nile Delta; Egyptian records of the Israelites bondage under Pharaoh; the precise route they may have followed to freedom; their crossing site on the shore of the Red Sea; and the location of Mt. Sinai. THE EXODUS REVEALED brings to light the first significant archaeological "find" of the 21st century.

Gombessa Expedition 4 Laurent Ballesta went to observe a gathering of thousands of groupers during the full moon of June 2014 (Le mystère mérou) in the southern pass of the Polynesian atoll of Fakarava, where he discovered a pack of over seven hundred grey sharks. How can this unprecedented density be explained? Could it be that social behaviors govern this wild horde? During three years of preparation, he and the other divers on his international scientific team tamed their fear by abandoning the defensive reflexes that provoke shark aggression, with the aim of slipping into the heart of the raging pack to study and film it from the inside. Sharks fitted with microchips, receiving antennas, hydrophones, an ark of 32 synchronized cameras...: a whole technological arsenal is mobilized for the project. As the groupers approach for their annual spawning, what battle plan will the sharks deploy?

On the other side of the world under the crystal clear blue waters of the Pacific Ocean lies one of the most enchanting places on the planet. Over ten thousand miles away on the north eastern coast of Australia lies the Great Barrier Reef, one of the natural wonders of our world. It provides shelter to some hidden wildlife sanctuaries that contain some magical marine creatures. Invited on a reef adventure by Emmy Award-winning underwater cinematographer and marine biologist Richard Fitzpatrick, conservationist and naturalist Iolo Williams dives deep beneath the surface of the coral sea to discover what state this natural wonder is in. Together they travel from the extreme swells of the northern part of the reef right down to the cooler pristine corals of the south. They discover how healthy the Great Barrier Reef really is in some of its key locations to see and find out if there are real signs of hope the reef can survive the threat of global warming.
