A horror story writer attempts to scare the Dragons into investing, but doesn't quite get the reaction he expects; in fact it's a reaction never before seen in the Den. There's a blast from the past as two Mancunian sisters who first walked up those infamous stairs back in 2005, are now asking for investment in their new gluten-free oriental dipping sauce range, but will it be a case of better luck second time around? And with the kids all back at school, two friends hope now is the right time for investment in their innovative children's backpack designs - have they got what it takes to part five of Britain's most successful business men and women from their hard-earned cash?

Also pitching to the multimillionaire investors is a Northern Irish inventor with his unique range of wearable luggage, and love is in the air when two Dragons tie the knot using a rather unusual vending machine.

Two graduates aim to impress the Dragons with their update to a 200-year-old invention, a product they believe creates a whole new way of advertising on Britain's streets. Will the pair's futuristic demonstration be enough to secure the cash they desperately need, or will the investors spot a fatal flaw?

A beauty lover from Birmingham pitches possibly the smallest product ever seen in the Den, and a Lancastrian father of three has some explaining to do when his business building wooden huts comes under close scrutiny from the five multimillionaires.

Other ideas seeking investment in Den include a multi-directional paint brush, a solution to the troublesome problem of 'pillow slippage' and a taxi driver's security invention, which is put through the Theo Paphitis break test.
