Laura Armbruister is posing as her own substitute teacher because the school administration wants to put an end to all this drama nonsense, but they can't close down the upcoming play until they find Ms. Armbruister to fire her. Meanwhile, a fellow teacher and admirer, Steve Clarkson, is doing what he can to help Laura keep her job. But one of the students gets the wrong idea and thinks the two teachers are eloping at lunchtime! The students decide to come up with their own plan to save the show, which includes having the lead, Dave, dress as Ms. Armbruister. Other characters include an overbearing mother, bumbling stagehands, an aspiring young playwright; two journalism students who can't seem to get a story straight; and of course the school administrators who become more frantic as the opening draws closer and closer.
