The final programme in the series and the Sea-Riders are back on board for OP-EX, a virtual reality war in which Superb is the hunter and the hunted. This is the final hurdle the boat and her crew will face in their long assessment. It's a pass or fail situation and tension is running high. And as dolphins play off the bow of Superb in the warm waters of the Med, the Captain has a hard decision to make, it's time for him to move on. This film was first broadcast: 11 Feb 2000
