Talented eleven-year-old actor Brad Simpson has just wrapped up a movie with several famous actors, but he's more than ready to settle down with a steady role on "The Pioneers", an exciting new TV show. Despite his growing friendship with his young cast mates, Brad senses something seriously amiss on the set. He experiences terrifying visions and threatening ghosts. When an accident nearly costs the entire cast their lives, the director is forced to shut down filming while the kids recuperate.

It begins to look as if the show won't make it to the screen...not unless Brad and his scared-but-determined co-stars team up to play a game of baseball against the Los Angeles Pioneers, a ghostly, doomed baseball team made up of failed actors from the late 19th century. Will Brad and his new friends solve the mystery of the ghostly field and successfully banish the spooks from the set to keep their show in production?
