Another hilarious adventure of the evil vizier Iznogoud! The kind-hearted and slightly chubby caliph Haroun El Pousah refuses to eat, and the Council of Wise Elders declares him unfit to rule. The first one to prove he is a relative will succeed him.

The always ready-to-rule Iznogoud begins the search for his ancestors, initially looking for his father, whom he barely knew. At the same time, he methodically eliminates all potential claimants, using the most despicable and horrific strategies...

Will he succeed this time in becoming caliph in place of the caliph?
