Barbie is no longer just a pretty face. She can do any and everything, and to prove it, she and her good friend Becky have just completed a training course at 'Detective Academy'. The fall carnival has come to town, and Barbie's boyfriend Ken in charge of the finances-money which will be donated to charity. But when he volunteers to help the magician with her disappearing act, he disappears for good-along with the charity money. Barbie and her parthers must search the carnival for clues that might lead them to find Ken, the missing money and the person responsible for their inopportune departure.
