Miss Nelson's class is the worst behaved in the whole school! Spitballs flying across the room, paper airplanes sailing every which way, and uncontrollable children send the gentle, long-suffering teacher, Miss Nelson, over the edge. But the students of Room 207 are in for a surprise when Miss Nelson turns up missing and is replaced by Viola Swamp, the scariest substitute teacher ever. In desperation, the students set out to find their beloved Miss Nelson... but will they ever get her? Enduring lessons of appreciation and respect from the creator of last season's hit production, Junie B. Jones and a Little Monkey Business!
