This film is a portrait of two passionate ice caves pioneers, explorer-glacionaut Serge Aviotte, and the scientist-glaciologist Luc Moreau.

Serge Aviotte, glacionaut, explorer, and caver (creator of the French School of Caving) has many expeditions to his name, from the French Alps to the glaciers of the two poles. He tells us about his obsession to descend ever deeper into the ice caves, called moulins, of the French Alps and in those of the vast Greenland ice sheet.
Luc Moreau, glaciologist, has specialized in the study of glaciers movements. Researcher in the laboratory of the EDYTEM - University Savoie Mont Blanc / CNRS, he has developed time-lapse systems to observe the advance of glaciers, and studies hydrology, meaning the flow of melt water in the ice caves.
This film is the story of the reunion, after more than 20 years, of Serge and Luc in the moulin of the ice sea in Chamonix, to the extreme caves of Greenland, but their goals are very different ...
