In the opener of this reality-competition series, in which survivalists must make their way out of an extreme environment and back to civilization, Jake, our former Navy SEAL, is ambushed and dumped atop a volcano in Iceland. Facing deadly avalanche fields, boiling mud pits and sulfuric geysers, Jake could lose more than the game when he makes a near-fatal error in the land of fire and ice.

Terry, our Green Beret, is ambushed on vacation and tossed out of an airplane into the middle of the ocean in the Gulf of Mexico. Facing the threat of dehydration and freezing conditions, will Terry's training help him survive the challenge and find land?

Matt, our primitive skills expert, is snatched from his surfboard and dumped into the Costa Rican jungle in his flip flops. Treacherous waterfalls, poisonous snakes and blood-sucking ticks abound. Will the jungle eat Matt alive before he can escape?

John, our extreme survival instructor, is put to the test as he's taken down in broad daylight and dropped on an Alaskan glacier with little more than a pool cute to defend himself. Can he navigate across the tundra before his body goes hypothermic?

Army Veteran Tom is captured, hooded, handcuffed, and dropped on a volcano in the wilderness of Chile. He’ll need all his bushcraft skills to scale glaciers, conquer an impenetrable jungle, and brave the desolation as he races to find civilization.

Primitive skills expert and endurance athlete Matt is captured and dropped into chest-deep snow in the Arctic circle. Wearing nothing but his buckskin shorts and sandals, he has to fight through a frozen swamp of snow to find his way back to civilization.

Extreme Survival Instructor John Hudson is gassed by the guys at his dentist appointment, extracted to the endless Canyonlands of Utah, and dropped into a 200-foot crevasse. Forced to confront a devilish maze of claustrophobic dead end passages, can he make it out?
