Made at the time of the opening of the Gotthard Tunnel—the longest underground rail section, the self-proclaimed “safest tunnel in the world”—the film was shot in a segment designed for evacuation exercises, and for tourist visits. A chance for safety experts, a therapist who uses hypnosis to overcome tunnel phobia, an actor who suffers from this phobia herself, or even an entrepreneur convinced of the future of underground transport to meet.
