The fakir Watziznehm arrives by flying carpet to ask the Gauls for help when the guru Hoodunnit threatens to end a terrible drought by sacrificing the lovely Princess Orinjade.
Asterix and Obelix set off to prospect for black gold in the Middle Eastern desert so the druid Getafix can create the magic potion which gives the Gaulish villagers superhuman strength.
Asterix finds an abandoned baby boy outside his hut, and even though he and Obelix have more experience fighting with the Romans, the two Gaulish warriors decide to raise the boy.
One stormy night, a sinister little man arrives in the little Gaulish village, and Prolix says he's a soothsayer and the villagers believe everything he says, but Asterix suspects otherwise.
