They are scientists, doctors, machinists and models. And one of them is a saboteur.

ABC has revealed the identities of the 12 contestants on its resurrected reality show "The Mole," which returns to the air on June 2 after a four-year absence (it's been six years since the last non-celebrity version).

The series, hosted by Jon Kelley, will kick off in Chile, where contestants will have to jump over the edge of a waterfall, among other challenges. And, as in past incarnations, one of the 12 players is the Mole, secretly working to foil the plans of the other contestants. As with the previous editions, the player who knows the least about the Mole in each episode is eliminated, and the winner stands to pocket $500,000.

The 12 players range in age from 24 to 60 and include a neuroscientist, a restaurant manager, a retiree and a musician. Viewers will have to figure out for themselves just who the Mole is, however; ABC is promising a heavy online presence for the show so viewers can play along.
