More and more people are taking up risky, adrenaline-fuelled sports like bungee jumping, skydiving and waterskiing and this documentary follows a group of people with disabilities determined to push themselves to the limit. Bazza lost the use of all four limbs in a car accident, Jenna was born with small arms, Caroline lost a leg in a motorcycle crash in which her husband died, Gemma is reliant on crutches and a wheelchair as a result of the rare Guillian-Barré Syndrome and Kain is one of the smallest dwarves in the UK.
