In sub zero temperatures 200 miles north of the Arctic Circle, Dutch Daredevil Wim Hof attempts to run a full 26-mile marathon clad only in shorts and a pair of sandals.

Hof currently holds nine world records for exposure to extreme cold, but this awe inspiring act of endurance surpasses all his previous adventures. Exposing the body to temperatures of -25C for more than four hours is an extraordinary challenge, one which experts fear is beyond the capabilities of human beings.

This film follows Wim’s preparations in Amsterdam, which include taking midnight dips in freezing canals and meditating in a meat freezer. It also examines how Wim’s extreme behaviour impacts upon his family life.

Tensions run high as Wim and family head north for the marathon. Everyone is aware that with this challenge Wim is taking on a level of exposure to cold far in excess of anything he has ever previously attempted. He is a Daredevil venturing forth into the extreme unknown
