Sharron and Richard are acting as bodyguards to visiting Eastern European president Drobnic and his wife and travel to Holy Loch in Scotland to inspect the submarine HMS 'Weatherby'. A gang of saboteurs have planted a bomb on board, which explodes, killing the captain and injuring the president as well as sending the submarine down to the bed of the loch. Craig senses that his colleagues are in trouble and travels to Scotland to hunt down the saboteurs. Sharron, who is medically qualified, has to save the president's life whilst Richard assumes the responsibilities of the captain. Unless the 'Weatherby' can be refloated, there is only enough oxygen to last for twelve hours so Craig had better work fast. Written by don @ minifie-1

Submarine sunk here
23 July 2012 | by (Ambrosia) – See all my reviews

Submarines featured prominently in three 'Champions' episodes - 'The Search', 'The Silent Enemy', and this - and with good reason. The producer had splashed out on a realistic set, and was determined to make good use of it. Donald James' 'Twelve Hours' starts with a Royal Navy supply van being ambushed on its way to the submarine base at Loch Trannith, Scotland. A mysterious box is placed aboard, and the police are told where to find the van. Visiting head of state 'Drobnic' ( Henry Gilbert ) is in Britain ( along with his talkative wife, played by Viola Keats ), and Tremayne wants Richard and Sharron to provide escort duty. Subversive elements in Drobnic's country want him dead. Part of the tour involves a trip around Loch Trannith in submarine H.M.S. Wetherby. As it sinks below the waves, a bomb goes off, killing the Captain, injuring Drobnic, and sending the sub to the sea bed. They have only twelve hours before the air runs out. The only way to escape is by using the pumping equipment. Barrett refuses to do so as Drobnic requires an immediate life-saving operation and the vibrations caused by the pumping will make it impossible. He comes into conflict with 'Raven' ( the late Mike Pratt ), a senior engineer, who wants the pumping to begin immediately and does not care if Drobnic dies or not. When Raven loses the argument, he and his men draw straws to see which one will murder the head of state...

A suspense-filled episode this, providing good roles for Richard and Sharron. Craig's main contribution to the plot is to telepathically transmit to Richard the information needed to operate the sub's pumping equipment ( most of the crew having passed out through lack of air ). It is interesting to see Mike Pratt before he became 'Jeff' in 'Randall & Hopkirk ( Deceased ). His character 'Raven' takes an instant dislike to Barrett, referring to him as 'our self-appointed boss'. There is a well-written scene as Raven and Barrett lock horns. Less impressive are the model shots of the sub on the sea bed, the scale of the bubbles giving the game away.

Also on view is the late Peter Howell as 'Admiral Cox'. Fans of 'The Prisoner' will recognise him as 'The Professor' from the classic 'The General' episode.

One of the 'Champions' comic strips in 'Joe 90 Top Secret' featured a sub which is stolen by villains wishing to destroy an undersea oil pipeline with a nuclear device - practically the same plot as the Bond movie 'The World Is Not Enough', only this was thirty years before!
