According to her, it contains the locations of the Dutch crown jewels hidden since World War II. Soon, Mitty finds himself in the middle of a confusing conspiracy, where he has difficulty differentiating between fact and fiction.

On the run after being found sweet-talking the Sultan's daughter, Aladdin comes upon a lamp which, when rubbed, summons up Babs the genie.

Unfortunately for him, the sultan's wicked twin brother has secretly usurped the throne, someone else is after the lamp for his own ends, and Babs has taken a shine to Aladdin herself and is bent on wrecking his endeavours.
