For more than 10 years BAFTA award-winning Martin Clunes (Doc Martin, Reggie Perrin) has escaped from the world of acting by diving on family holidays in the Maldives, experiencing the silent universe he has found undersea universe with its vivid colors and its alien inhabitants. However, one resident of these warm, blue waters has so far eluded him - the reef manta, one of evolution's true masterpieces, massive creatures which can weigh as much as 5,000 pounds with a wingspan of up to 25 feet. Clunes seeks overcome a recently acquired diving anxiety and fulfill his ambition to swim with the sea's most enormous and enigmatic of creatures.
