Marsha Steele is at it again. When she volunteers to help the high school librarian with a book fair, Marsha stumbles across the woman's body and is roped into running the book fair alone. Marsha comes up with the great idea of doing the fair along with a harvest carnival. The main attraction is a Haunted Tunnel. Little does she know, but evil lurks inside the tunnel that has nothing to do with scary costumes. Join in as once again Marsha and a cast of zany characters try and catch a killer before they become the next victim.
