Rob will use his self-proclaimed “extensive knowledge of everything” to explore a mystifying legend that takes him on an epic adventure around the world each week. He’ll meet local guides to help him along the way and invite people who don’t think he’s up to the challenge to accompany him, eventually proving them wrong.

Relying on his mental toughness and self-taught high-performance karate, Riggle will take on some of the biggest challenges and most daring adventures he’s ever faced.

Riggle’s adventures will take him near and far – from traveling to Scotland in search of The Holy Grail to diving in Greece for the lost city of Atlantis and jetting off to Key West to look for a pirate’s hidden treasure.

Fearless in the pursuit of adventure, Riggle will put new skills to the test, try new delicacies and meet new people as he travels the globe investigating one epic mystery at a time.
