In this episode, we gain unprecedented access into the life of James Caan. We discover why his daughters cringe at some of his appearances in the Den and get a glimpse into the jet-setting lifestyle of a multimillionaire businessman as he breakfasts with his wife in Cannes, checks up on some business investments in Lahore and gets an update on his latest venture aboard his own luxury superyacht, specially designed to meet James's meticulous demands.

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.

In the final programme of the series, it is Duncan Bannatyne's turn to open the door into his multi-millionaire world. Having grown up in the shadow of the shipyards of Clydebank, he makes an emotional visit to the local pub where he used to play dominoes with his father and talks about some of the events that shaped his life. We see a very different side to the tough-talking, plain-speaking dragon as he explains how his unconventional CV is ideal for anyone who wants to be a successful entrepreneur.
