Australian Jon Muir is one of those super-fit, super-motivated and slightly barmy people who can’t help setting themselves one hardcore challenge after another. Having already gone up Everest (solo), been to both Poles and fought off a polar-bear attack, he turned to his biggest challenge to date: a 1600-mile solo walk across Australian desert. Well, not entirely solo – he’s taking his Jack Russell, too. The population across the entire route is 100 people; it’s something he’s been planning for 14 years and he’s already aborted three attempts. Will he make it this time? This film tells the tale of an eminently likeable chap and the man least likely to opt for a fly-and-flop holiday.
