It's Peter Jones' story next in the penultimate programme in this series. He made his money in the telecoms industry, but has gone on to become one of the most high-profile businessmen in the UK. With unprecedented access to Peter's business and personal life, we follow him as he visits 10 Downing Street for a meeting with the prime minister; at home with his five children; and discover how he made, and why he lost, his first fortune.

We also catch up with some of Peter's investments, which are among the most memorable in the Den. Both Levi Roots and his Reggae Reggae Sauce have become household names, but how much money are they making? And Hamfatter, the first band to enter the Den, ended up being able to choose between offers from four dragons. Peter won that battle, and we catch up with them all during the band's recent UK tour and discover whether their dragon backer has managed to turn them into a profitable proposition.
