Four best friends ...two spooky sleepovers ...and one ghostly guest! When a guest at Mayfair Park claims her room is haunted, Lauren and her friends are convinced there must be a rational explanation. After all, there's no such thing as ghosts, right? But the crew of top TV show "Mostly Ghostly" disagree, and insist on investigating the paranormal puzzle. Will the girls be able to persuade this ghostly guest to check out of Mayfair Park - for good?
