There's a piratical mood for antiques experts Raj Bisram and Irita Marriott as they set sail on their final outing together. There are shops to plunder and booty to be bought as they explore the very tip of the Cornish peninsula. And with the competition being so close at this point, the pressure is on to find that auction-winning item.
Raj makes some big finds in one of the tiniest shops of the trip and pins his hopes on a risky item that may or may not be highly collectable. Irita plays Raj at his own game, plumping for a very cheap purchase and finding a painting that reminds her of her childhood and also contains a hidden secret. Along the way, there's still time for some sightseeing, kite flying and, of course, pirate impressions.
In a break from antiquing, Raj heads to a famous tavern to hear about a Cornish folk tradition full of mystery and mischief, and he gets roped into a spot of dancing. Irita heads along the promenade to find out where the residents of Penzance go for a dip and gets to discover first-hand just how cold sea water can be.
Then it's off to the final auction with their prized possessions to see who will seize victory and who will be walking the plank.
