The Mariana Trench — Matt Shaw

Thousands of climbers have successfully managed to scale Mount Everest, the highest point on Earth. Only a handful of divers have descended to the planet's deepest point; the Challenger Deep in the Pacific Ocean's Mariana Trench. Over the last few months a series of earthquakes have been rumbling from deep within the trench. Curious to know why, and the impact they are having, a team of scientists start an expensive expedition down into the depths. Funded by a billionaire - who is going along for the ride in his specially designed submarine - the team head beneath the ocean's choppy waves with the world watching. Little do they know that 7 miles beneath the ocean's surface, their nightmares await and their world will never be the same again.
