Five surviving Little Sisters of Hoboken discover that their cook, Sister Julia, Child of God, accidentally killed the other 52 residents of the convent with her tainted vichyssoise while they were off playing bingo. Upon discovering the disaster, Mother Superior has a vision to start a greeting card company to pay for the burials. Unfortunately Reverend Mother spends the profits, and the nuns stage a variety show in the Mt St Helens School auditorium to raise the money!
