Movies and TvShows featuring "the-other" theme.

Two friends, Kevin and Luke, embark on a hiking trip deep into a forest to escape their hectic lives. When Luke receives an urgent call from his boss, he reluctantly leaves Kevin behind. Alone in the woods, Kevin discovers a mysterious, glowing red mark on a tree. Is it merely a mundane symbol, or could it signify something far more sinister—a territorial sigil that awakens an ancient deity of the forest?
