A strange Asian woman is the prime suspect in a number of deaths aboard a ship.

Since neither Val's parents nor Sabrina's aunts will allow them to have a car, the two teens cook up an ingenious scheme to share the costs and responsibilities for a single vehicle. Working their timetables to fit puts an intolerable strain on their friendship, however; and when the car conks out, Sabrina gives in to Salem's suggestion and buys a car for a ridiculously low price in the Other Realm. Trouble is, this old clunker has a mind and a voice of its own, which makes hiding it from Sabrina's aunts a real problem, particularly when it keeps transporting itself to her bedroom. Meanwhile, Hilda and Zelda are distracted by their own problems: they are being audited, and discover that their trusted accountant Marty has skipped town with all of their magic.
