Synopsis

Qu'est-ce qui se passe quand...? is a documentary series in which Sébastien Kfoury explores nothing less than the limits of the human body. What happens when you stop sleeping altogether? When we're deprived of all human contact? Or when we're confronted with our greatest fears?

Today, more than ever, the human body has to adapt to ever more extreme conditions: overstimulation, intense heat, stress, pollution or incessant noise. And these challenges are only growing. A masterpiece of engineering, the human body demonstrates an incredible capacity to adapt and push back its limits. But what happens when these limits are exceeded?

Our scientist will do his utmost to answer these astonishing questions by subjecting himself to these extreme conditions, meeting humans who have reached or even surpassed these limits, interviewing scientists who are experts in the field, and examining the most extreme tests carried out in recent decades.
