An insightful documentary charting the business career of Hilary Devey, the newest star of Dragons' Den, explaining how and why she achieved the success that she has.

A young businessman from Lancashire hopes to convince the Dragons to part with the biggest cash investment ever achieved in the Den and increase the fortunes of his family's shoe business; a Scottish surveyor pitches her kitchen product which was inspired by a knight in shining armour; and two ambitious friends think they've devised the next Rubik's cube, which they present with some imaginative theatrical mimes.

A bride and her business partner climb the stairs to the Den seeking long-term commitment from a Dragon. Will their novel idea, capitalising on the wedding market, be enough to forge a union?

Elsewhere, a Bury-based businesswoman demonstrates her beauty product with the help of her daughter; a Hertfordshire entrepreneur hopes his million-pound turnover will impress the Dragons; and a first-time inventor brings a bit of Shakespeare into the Den whilst pitching his balcony accessory.

Two Manchester-based business partners hope their unusual garden pods will create a stir, two revolutionaries have a plan to revitalise the UK housing market, and two of the youngest entrepreneurs ever to face the Dragons think their record label can take on the giants of the industry.

Elsewhere, a husband and wife team think they have designed a must-have accessory for women, and an entrepreneur from Glasgow is on a crusade to turn the Scottish national dish into a fast food snack.

A former milkman pitches his balance bike business accompanied by his three-year-old daughter, will a little person in the Den help persuade the Dragons to invest? Three London-based friends present their hands-free pint-pulling product, and a grandmother from the Isle of Wight, demonstrates a modern take on the ancient Greek practice of swinging... There's also a potential solution to help aid a common problem experienced by babies...nasal mucus extraction.

There are mixed fortunes in the Den this time as fashion-conscious twins try to persuade the Dragons to buy into their clothing range, a Teesside-based entrepreneur has a run-in with the investors over his decision to separate out the assets in his company, and a former firefighter asks the Dragons to invest in a car that thinks it's a bike.

One multimillionaire also gets their feet wet while trying out a beauty treatment administered by fish, but will a bit of Dragon pampering lead to a clean sweep of offers?

This time all the world's a stage and the Dragons merely players when two business partners from Lincolnshire pitch their pantomime company. But by turning the Den into a makeshift theatre, can they prove that show business and financial business really do mix?

Elsewhere, one entrepreneur uses his pitch to tell the Dragons a story about growing up in South Africa, rather than concentrating on facts and figures, but how will that go down with the multimillionaires?

Plus two joggers enter the Den to pitch their fast-paced delivery service; and a young mum offers a solution to everyone's outdoor toilet needs.

A former disc jockey has a strategy, dress to impress to catch the attention of an investor. The DJ may have worn a DJ, but is that all it takes to part a Dragon from their cash? A Londoner hopes to alleviate a common worry for holidaymakers by locking up their valuables, but with just 5 per cent of his company on offer, can he guarantee a valuable return? Monterrey-born Marcela Flores Newburn pitches her Mexican food range complete with a full mariachi band, another budding entrepreneur asks the multi-millionaires to think of their homes, not as houses but as a source of income, and a former hairdresser has a product that makes money from thin air, but does he have the business plan to match?

It's a Den full of family businesses. Tim and Meena Kalia and their business partner Tricia Tierney try to talk the Dragons into investing in their innovative litter trays for dogs. The Den is taken over by a pirate, a street urchin and a hippy as Peter and Michelle Hart, plus five of their seven children, pitch their fancy dress business; but is their dream of investment pure fantasy? Brothers Jim and Richard George from Malvern believe they're in a strong position with their fence preservation company, which is already trading. The business-savvy siblings have a deal in mind - but will the offer they're holding out for materialize?

Others looking for Dragon investment include an 'all you can drink' membership club, an exercise suit that claims to burn extra calories, and some giant knitting needles.

This episode sees Londoners Krissy Sims and Kerry O'Brien AKA DJ Trickles and Lady MC enter the Den with a state-of-the-art turntable extravaganza in the back of their 4x4. The Dragons are often happy to demo a product but it is the business and how it makes money that remains their ultimate concern. Husband and wife team Liz and Alan Colleran from Dewsbury may be pitching their comfy caravan product - but will their Den experience be quite so luxurious and comfortable?

Elsewhere, an Englishman, a Norwegian and a Scot walk into the Den. Shades for canines are on offer, there's an inflatable car-based device like you have never seen before and a Kent-based entrepreneur thinks honesty is the best policy when pitching without a formal business plan - but with an offer to help everyone get the perfect looking body for just 20 pounds.

34-year-old Georgette Hewitt, from Kent, finds out exactly how nerve-wracking it can be to climb those famous stairs and pitch to the Dragons. It's a real battle to compose her nerves, but one she must win in order to tempt the multimillionaires to invest in her answer to a common birthday party headache familiar to all parents. Entrepreneurs often take advantage of the latest government schemes and incentives when building their business, which is exactly what Chris Hopkins from Yorkshire has done by capitalising on the solar power feed-in tariff. But when a Dragon knows your industry inside out it's not always what you want. Add into the mix the most unusual use you could ever think of for a plastic egg, a circus act that's sure to go with a bang, and a mind coaching massage service, and you've got a formidable showcase of the Great British spirit of invention and innovation.
