The annual Christmas Carnival is in town and Alyson and the gang volunteer to help out. When strange things begin to happen at the carnival, they wonder if the events might be related to the body they found in the cemetery earlier in the month. When Alyson has a potentially fatal accident on the Ferris Wheel, the gang is convinced that someone is out to make sure they don't discover the cover up that runs so deep that even highly respected town residents are involved.
