Her client is accused of murdering his wealthy wife and he his alibi is that he was staying at an inn while suffering from "kanashibar" (sleep paralysis). The only witness able to corroborate his alibi is the 500-year-old ghost of the Sengoku period military commander Rokubei Sarashina (Toshiyuki Nishida) - who sat on the accused's chest all night long. Attorney Emi Hosho travels to the inn to investigate further. Emi Hosho also falls into "kanashibar" and soon discovers the 500-year-ghost sitting on her chest. Knowing that the ghost is the only witness who can support her client's alibi, she grabs his hand and pleads with him to testify in court.
