Zach fell in love with the show Survivor at an early age and started learning how to survive on his own.  This included mastering Aikido to help deal with bullying after both his obsession with the show as well as is orientation became known.  When he started doing solo treks to develop his skills, he did them nude for the most part, initially as a self test, then continued when he discovered it was a far more comfortable way to be.

In his 20's, he arranged to be dropped off on a deserted tropical island for a month to survive on his own.  While there, the Cascadia Fault slipped, triggering a large tsunami that devastated the lower parts of the island.  It also killed the people that knew he was on the island, leaving him stranded, but out of contact, he had know way of knowing why they never came to pick him up.

Ben was doing a solo round the world sailing trip when a storm shipwrecked him on the island.  They have to push down their independent streaks and work together to rebuild the boat and escape...or maybe decide to stay and make a life right there.
