Nevin Galmarini won gold in the parallel giant slalom at the 2018 Winter Olympics. In the following season, however, a slipped disc forced the snowboarder off the slopes and on the long road back.

The film "Mental Hygiene" accompanies the equally passionate mountain biker on his tour over the Piz Clünas, where he recharges his batteries for his comeback on snow.
