If the Sun Never Returns (1987)

In a remote Swiss mountain village, the self-proclaimed prophet and sorcerer Anzevui foretells that the sun will never return, plunging the community into eternal winter. As fear and panic spread among the villagers, most succumb to despair. However, a young woman named Isabelle courageously resists the collective hysteria, ultimately rallying a group to ascend above the fog-covered valley in search of the elusive sun.
