No sooner does she arrive at the set than the movie's other star, the champion racehorse Orion, disappears without a trace. Has Orion been stolen? It seems like everyone had a motive for wanting the horse out of the picture. Can Barbie find the real culprit behind the crime in time to save the movie?
