The Hero is like a TV version of a box of Wheaties. TNT's new competition reality series, hosted by Dwayne "The Rock" Johnson, makes you want to climb tall buildings, crawl through tight spaces and run wild through the streets. Filmed in locations throughout Panama, the extreme sports-style show pits nine competitors against each other for a potential $1 million prize.

This year's contestants include pro wrestler Shaun, LAPD officer Charles, personal trainer Lydia, former NFL cheerleader Athena, scale technician Darnell and salon assistant Patty, a self-described serial crier. "I'm the world's bravest chicken; that's what I said in my audition," Patty, 46, tells TVGuide.com. "I have been afraid of everything my whole life. I can still overcome things, even at my age."

Contestants participate in two challenges per week — a team challenge and a hero challenge, which is undertaken by one contestant chosen by his or her peers. If the six-person team is successful, time is added to the hero challenge, and $10,000 is given to the American Red Cross. The "hero" then attempts to win money for the team's collective pot, but also has the option to keep the money for himself or herself. "The arch enemy of integrity: temptation," The Rock explains in a voiceover, smiling broadly. "What would you do?" At the end of The Hero's eight-week run, viewers will pick one winner to receive all of the money in the team pot.

In the premiere episode, the challenges include scaling the face of the 837-foot-tall Towerbank Financial Center in Panama City crawling through a dark maze — and tarantulas! — inside Gen. Manuel Noriega's former bunker.
