A young woman ventures into a decrepit dance hall during peacetime to film a television program, only to find herself overcome by sudden illness and a haunting vision of another girl in crimson—a stranger whose features mirror her own. As the boundary between reality and hallucination blurs, she begins to suspect that this doppelgänger might be more than a phantom of her fevered mind, possibly representing a connection to her own forgotten history. The encounter sets in motion a mystery that forces her to confront questions about identity, reincarnation, and whether the past can reach across time to reclaim her.
