It all starts at a hammam. In the steamy bath, a French teenager discovers Arab sensuality at its best, like a thunderbolt. But when his young Moroccan leaves the building, he becomes invisible in the casbah's alleyways. Our young hero sets out to follow him through the busy streets but, too far behind him, he gets lost in the souks where he will discover, in the back rooms of shops, the very particular hospitality of Eastern traders.
