Five of the 19 surviving Little Sisters of Hoboken, a one-time missionary order that ran a leper colony on an island south of France, discover that their cook, Sister Julia, Child of God, accidentally killed the other fifty-two residents of the convent with her tainted vichyssoise while they were off playing bingo with a group of Maryknolls. Upon discovering the disaster, Mother Superior had a vision in which she was told to start a greeting card company to raise funds for the burials. The greeting cards were an enormous success and, thinking there was plenty of money, the Reverend Mother bought a home entertainment system for the convent, leaving her with no money in the kitty to pay for the last four burials. With the deceased nuns on ice in the deep freeze, they decide to stage a variety show in the Mount Saint Helen's School auditorium to raise the necessary amount. Participating in the project are Mother Superior Mary Regina, a former circus performer who can't resist the spotlight; her competitive but dignified rival, second-in-command Sister Mary Hubert; Sister Robert Anne, a streetwise nun from Brooklyn; Sister Mary Leo, a novice who is determined to be the world's first ballerina nun; and wacky, childlike Sister Mary Amnesia, who lost her memory when a crucifix fell on her head. The entertainment that they present includes solo star turns, madcap dance routines, and an audience quiz.
