Les Hommes de l'Extrême are mountaineers, and they are also building workers and tree croppers. They are working at the Grotto in Lourdes for the next few weeks - until 8 February - cutting back the tree branches to ensure that the rock face is safe.
The film by Laurent Jarneau, along with many other films about Lourdes, can be seen on LourdesWebTV at: www.youtube.com/user/LourdesWebTV
It can also be seen on the official Lourdes site, which has a great deal of information about Lourdes, and real-time film of the Grotto, the Domaine, Masses, and prayer events there. See: www.lourdes-france.org
