Inspire through the teachings and emotions of Tethys
112
What if an incredible journey through the Alps could mirror the climate challenge?
This is the metaphor of a daring adventure by a young climatologist from Ljubljana to Nice, from the great peri-alpine lakes to their sources.
A 112-day journey covering nearly 3550 km, hiking and swimming, in semi-autonomy, punctuated by over 100 water measurements and samplings, aimed at addressing the disruptions of mountain water cycles due to climate change and the impact of human activities. But beyond this physical and scientific quest, Tethys embodies the poetic and radical commitment of this young climatologist. Immersed in the researcher's intimacy, we explore his deepest emotions and reflections, fueled by the power of endurance that defies the impossible. A vibrant initiatory journey of resilience and hope.

An artistic and participatory approach
The documentary film aspires to be a tool deeply rooted in reality, capable of marking our imaginations to mobilize in favor of a metamorphosis of our society. It offers a perspective that is both enlightened and sensitive on the consequences of climate change in the mountains, where testimonies from the field resonate with scientific messages.
This film stands out for its innovative approach, skillfully combining the epic journey across the Alps with dance sequences, which give it a unique artistic dimension. By integrating poetry, dance and music into the adventure, it infuses the story with a particular emotional force. The dance sequences, shot in a studio and enhanced by black and white treatment, seek to animate the immaterial by giving substance to the emotions experienced throughout the journey.
The documentary thus powerfully conveys the climate challenge and the upheavals in the water cycle in the mountains, drawing on the energy of the body to express the scale of these issues.

"I gently stroke the wheat along the path, feeling my hand brush against the drops of water beading on the foliage. My gaze then climbs the slopes almost touching the sky; my eyes narrow as the glaciers illuminate them, water is everywhere. But for how long? Water has shaped the valley through which I run, the shores of this lake, the sides of these mountains, and down to the depths of our valleys. Making the connection, yes, joining water to mountains is not a whim; it is the natural course of things. The Tethys project aims to return to the source, to what keeps us alive."
