Expanse - ABC Australia

In 1999 a young American dumped his bicycle and walked out into the Great Sandy Desert in remote northern Australia. He was an Alaskan firefighter, seemingly with everything to live for. So why did he risk it all to go into the wilderness alone? And how do you search for someone who doesn't want to be found?

In 2022, host Erin Parke became obsessed with the saga of Robert Bogucki, which became a media circus and prompted everyone involved to think about life, death and who we are when everything easy is stripped away. It's a story that spans three decades, two continents and a bizarre cast of characters. From booty-wearing bloodhounds, to a larger-than-life, cigar-chomping American named Gunslinger, the search for the missing man became a spectacle in itself.

In season 5, Expanse: Nowhere Man, Erin sets out to discover why some people are pushed to lose themselves in the wilderness on a search for meaning. At a time when so many of us feel lost, just how far would you go to feel found?
