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 gentle, long-suffering Miss Nelson over the edge. But the students of Room 207 are in for a surprise when Miss Nelson goes missing and is replaced by Viola Swamp, a no-nonsense substitute who assigns piles of homework! The students learn lessons of appreciation and respect as they set out to find their beloved Miss Nelson … but will they ever get her back?
