With the Den closed for business, the multimillionaire investors are off on their first tour of the UK to find out what happened next. The Dragons drop in on some of the most memorable businessmen and -women from the Den. They discover which of their investments are thriving, how those entrepreneurs who were not so fortunate are getting on, and keep a wary eye out for any businesses they wish they had backed.
The tour heads south, featuring the colourful father-and-son team behind Ladderbox, the opening of pop sculptor Guy Portelli's exhibition, and olive oil enthusiast Michael North, who dared to take on Deborah Meaden during his time in the Den.
Peter Jones catches up with one of his investments, Rachel Watkyn from Tiny Box Company, and the Den Destroyer Theo Paphitis drops in on the man behind one of the most popular products not to get investment - Rob Law's Trunki - to find out if he was wrong to not invest.
