Summary: Contestants must put on a brave face when they are pushed to their limits in hopes of winning $100,000. In the first stunt, contestants are ripped off a cliff’s edge and sent hurtling into space on a bungee line attached to a helicopter 500 feet away. Highlights from subsequent stunts include contestants being submerged in a tub full of leeches before having to consume 10 leeches; teammates working their way up a five-story building engulfed in flames, before being rocketed off the roof in an enormous explosion; and, teams facing their fears as they are confronted with the challenge of being tear gassed, tattooed or having their head and eyebrows shaved.
