In Tamazight culture, "Twïza" symbolizes a gathering for sharing and mutual support. This is precisely what Thibault Dion's film explores – January 2019 – as five French climbers land at Constantine airport. While they initially thought they would simply be opening climbing routes in eastern Algeria, this group of climbers from Grenoble discovers much more. Their initial apprehension about exploring this isolated region, coupled with the warm welcome, good humor, and rich culture, transforms their journey into an unexpected human adventure. Fabulous landscapes, thrilling experiences, unforgettable moments, smiles – beyond borders, in the land of friendship and hospitality... Algeria.
