A criminal is traveling with a carnival, committing crimes up and down the West Coast. Private investigators Michael Walker and Brianna Taylor return to Yakima, in eastern Washington, searching for clues in the murders of three western Washington teens that may be related to the carnival. They team up with Detective Andy Carlson when a teen disappears while attending the carnival. The last person know to have seen the girl was a psychic who travels with the carnival. A polygraph clears Laurel Phillips of involvement in the girl's disappearance, but when the teen's body is found at a construction site Andy can't help but wonder if she is an accomplice. As the body count rises the murderer begins to stalk the carnival workers themselves, including Laurel's best friend. Digging deeper into the mystery puts the three friends' lives in danger, and leaves them to wonder who will survive the mad man's reign of terror.
