Five miles high in the Death Zone, Team 1 sets off for the summit at midnight in temperatures of minus 30 degrees F, filmed by high-intensity, infrared Sherpa Cams. But before the sun rises, Tim falls and snaps two bones in his left hand. He's in big trouble. Any accident in the Death Zone is potentially fatal, but Tim has decided not to radio expedition leader Russell Brice because he knows he'd be ordered to turn around. He's now gambling with his life, hoping he can make it up and down with only one good hand.
