A Ghost of a Chance(2011)

Defence lawyer Emi is assigned to a particularly unusual case: a man is suspected of murdering his wealthy wife, and his only alibi is a 421-year old ghost, Rokubei. At first Emi is hesitant, but when she pursues her lead she is visited by the ghost herself. And so the fun begins in the courtroom when Prosecutor Osano starts to cross examine.
