Part one of two. Following the critically acclaimed series Without Limits: Vietnam, and to mark the 2018 Invictus Games in Sydney, this observational documentary sees a team of injured British and Australian veterans - Martin Hewitt, Shaun Stocker, Keanie Trick, Matt Tolson and Dean West - embark on an extraordinary 1,000-mile expedition across Western Australia's remote Kimberley region with the support of HRH the Duke of Sussex. The team's route follows the Gibb River Road, an old stock route of mostly unpaved road. Spreading over Australia's entire north-western corner, the Kimberley is three times larger than England but with a population of less than 40,000.
