It's the most wonderful time of the year at Pleasantville Elementary -- but that doesn't mean that all is calm. A mysterious gift winds up spreading more than Christmas cheer as student after student turn into mutant zombies. Where did this gift come from? Who is behind it? How can it be stopped? And how does a lava lamp fit into all of this? It's up to the Lunch Club to save Christmas -- if they can save themselves first!
