This time Stan wants Daniel to investigate four people who claim to have superhuman heat tolerance, performing potentially deadly demonstrations that push themselves, and the human body, to new limits. Daniel puts them to the test to find out if they really can stand the heat! Ted Batchelor claims he is fireproof. At Salinas Airfield, Ted attempts the longest full body burn of all time, running over 500 feet, whilst burning at temperatures of 2400 Fahrenheit. Kann Trichaan from Thailand is rumored to be immune to the searing heat of boiling cooking oil, and appears to feel no pain, even when submerging his hands for seconds at a time. Anandita Dutta Tamali is the most chilli-proof human on earth, but can she withstand pepper spray? Marshall Ullrich is said to be immune to the lethal effects of heatstroke, but Daniel tests his heat tolerance by challenging him to run in potentially fatal temperatures, in an oven!
