Plot synopsis: Decades after a shocking serial murder case involving the swapping of spouses, a stage production based on the real-life crimes is being prepared. Inexperienced actor Tada is cast in the lead role, but as he becomes increasingly consumed by the character and begins to blur the line between fiction and reality, his obsession draws the play's cast and crew into his increasingly disturbing delusions. As opening night approaches, the boundary between truth and fiction collapses, leaving everyone to question what is real and what is imagined.
