Nanki-Poo has banished himself from the little town of Titipu because he is hopelessly in love with the beautiful young lady, Yum-Yum. Yum-Yum however, is engaged to her guardian, Ko-Ko. Upon learning that Ko-Ko has been condemned to death for the crime of flirting, Nanki-Poo returns to Titipu to claim Yum-Yum's hand. After an odd turn of events, it turns out that Ko-Ko has not only been reprieved of his death sentence, but has earned a promotion to the post of Lord High Executioner. Unfortunately, he is not a big fan of killing people. With the Mikado of Japan becoming increasingly annoyed at the lack of executions taking place, Ko-Ko makes a deal with Nanki-Poo. He allows Nanki-Poo to marry Yum-Yum for one month, as long as he is executed after that month. Complications arrive though, when it is discovered that a condemned man's wife must join her spouse in death by being buried alive.
