Mandao (Man-Day-Oh) of the Dead is a supernatural comedy about the unambitious Jay Mandao who lives frugally off his late father's cereal royalties. He wants nothing more than to live in solitude, but is duped into taking in his adult nephew-in-law, Jackson. As Halloween approaches, Jay begins having odd dreams and hallucinations, only to find out that he has the ability of astral projection. Jay and Jackson are approached by a ghost who has a small window of opportunity to reverse his death at the hands of Jackson's murderous ex-girlfriend.
