Adventurer, zoologist, big cat trainer and all-around risk taker Dave Salmoni hosts ABC's epic summer series, "Expedition Impossible", which features ordinary people doing the extraordinary in the biggest adventure of their lives. The show will feature 13 teams of 3, racing on an expedition across vast deserts, over snow capped mountains and through raging rivers. Each week a new stage of the expedition will be revealed to the teams. Will they crumble under the pressure of having to think clearly in the wilds of the great outdoors, or will they find a way to work together to complete their adventures? After 10 stunning legs of competition, one team will cross the finish line first to claim victory.
