The Little Sisters of Hoboken have been invited to sing at the Hollywood Bowl. They are thrilled at the prospect until they arrive and learn that they are booked into the Hollywood Bowl-A-Rama, a bowling alley with a cabaret lounge, not the famed Bowl they were planning on. The show is structured in the tried and true variety format, but as always, things go awry. The Sisters have to contend with announcements from the bowling alley public address system as well as the activity on the lanes, which is occasionally heard but not seen. Midway though the first act, someone get wind of the fact that the famed movie producer, James Todd, is across the street auditioning for roles in his new movie musical, "NUNSET BOULEVARD: A Song from the Hart," about the life of Dolores Hart, the famous movie star who became a nun. The Sisters, thinking they are naturals for parts, race off to audition during their own show's intermission. In the second act, woven through the planned numbers are updates as to what has happened with the audition. In the end, of course, the Sisters all realize that their true calling is as nuns, and they head back to Hoboken to work with their students on the premiere of the school's new show, "The Catholic High School Musical".
