The Order of the Little Sisters of Hoboken take over a high school auditorium to hold a fundraising variety show to raise money to bury several sisters (who were accidentally poisoned by their cook). They must inter the nuns before the health inspector comes and finds the dead nuns in their freezer! Fraught with hilarity, both Catholic and otherwise, we watch as five nuns try to perform their planned performance amidst chaos and calamity.
