Ernest P. Worrell (Jim Varney) is working as a garbage collector in a small Missouri town. Despite the warnings of superstitious local Old Lady Hackmore (Eartha Kitt), he accidentally unleashes devious troll Trantor (Jonas Moscartolo), a slimy creature confined under a tree for 200 years. Trantor changes some kids into wooden dolls and turns Ernest's dog, Rimshot, into a log. Ernest then teams up with Old Lady Hackmore to get rid of the beast and bring the victims back to life.
