When the yearly carnival arrives in Boo, Pennsylvania, Amanda and Billy think it's just the thing they need to get their minds off of everything they've been through. Pumpkins attacking people, zombies running amok all over town...their lives are far from normal and there seems to be little time to just have fun.

Unfortunately, evil never rests.

A mysterious fortune teller warns them of impending doom their very first night at the carnival, and when the town's children start acting strange, they know something dark and sinister is afoot.

With Mr. Night on their side, it's up to Billy and Amanda to get to the bottom of things and stop the madness before it gets out of control, or suffer the consequences.

It's time for another terrifying adventure in the town of Boo!
