This two-part documentary follows the journey of six people across Vietnam: six people who all have disabilities. The sextet are split into two trios: one in a 4x4 with Vicky Blach, who lost her leg in a rollercoaster accident in 2015; Mary Russell, who was born with the most common form of dwarfism; and paralysed Olympic wheelchair rugby captain Steve Brown. Meanwhile on motorbikes are deaf Louise Halvey; one-legged marathon runner Charlie Lewis; and one-armed professional biker Andy Slade. Among the challenges faced include Louise having to negotiate traffic in Hanoi despite her lack of hearing; and Vicky having trouble with her car due to her breaks failing. Without Limits: Vietnam is on BBC One at 21.00.
