In a dark and mysterious corner of Japan, a group of friends ventures into the famous Aokigahara Forest, also known as the "Suicide Forest." Sara, a young American woman, receives the news that her twin sister has gone missing in this eerie place. Without hesitation, Sara decides to leave everything behind and travel to Japan to find her.
Armed with determination and an indomitable spirit, Sara joins two locals: a journalist intrigued by the nature of the forest and a guide who accompanies her through this chilling landscape. As they delve deeper into the forest, the atmosphere becomes increasingly unsettling. Sara begins to experience strange visions and feels an ominous presence around her. Shadows seem to come alive, and her own mind becomes a battleground between reality and madness.
With every step she takes, she confronts her own demons, wrestling with fear, guilt, and despair. As she searches for her sister, she uncovers the tragic history of the lost souls that inhabit the forest, prompting her to question her own sanity. As the tension escalates, Sara finds herself caught in a macabre game where the only way to escape is to confront the dark secrets that have been buried beneath the surface, and where hope intertwines with horror.
