The Tridentine Society of Alpinists (SAT) was founded over 20 years ago by Nepomuceno Bolognini, Prospero Marchetti and 27 other members. Today, it has over 20 thousand members, divided in 75 branches, which confirms the popularity of such associations in the Trentino Valley. The film, with past images and interviews, shows the life and history of this reality that has no equal in Trentino. The object is to pass to others the sound search, the study of the mountains; a voluntary conservation commitment, the culture and solidarity of the mountain people are based.
