Ross Kemp: Shipwreck Treasure Hunter

Ross heads to Portsmouth and the Mary Rose Museum and takes up an opportunity he can't turn down, to be one of the few divers allowed on the site of Britain's most famous wreck, the Mary Rose.

Ross hops round the coast from Portsmouth to Plymouth, then on to the Gulf of Suez. A bout of hypercapnia leaves Ross shaken after the dive of a 17th century shipwreck.

The quest continues in the Red Sea off the coast of Egypt, a deeply personal journey given Ross' grandfather fought in the North Africa campaign during World War II.
