Entrepreneurs brave enough to climb the infamous stairs into the Den should not expect an easy ride. With the Dragons investing their own money, only the best ideas and inventions will secure investment from five of the country's most influential multimillionaires. With everything at stake, who will be victorious this time? For Lancashire-based Paul Ward, the current swine flu pandemic has boosted sales of his bug-busting cleaning products, but will the Dragons be impressed enough to invest? Carol Savage from Hertfordshire hopes to cook up a frenzy with her online community for food lovers, and whilst the Dragons are no strangers to fine wine, can serial entrepreneur James Nash entice them to pour investment into his innovative single serve wine containers? Meanwhile, can jewellery and fashion designer Jane Rafter walk away with investment for her range of customisable sandals? Finally, the Dragons come face-to-face with themselves as a Midlands trio ask for 50,000 pounds for their customisable masks.
