The people of Djenné (Mali, Africa) end the dry season with a special tradition. They plaster their mosque. This fairy-like building is the largest adobe construction in the world. Due to high temperatures and the (scarce) rainfall it erodes quickly. To prevent the Grande Mosquée from 'melting down' to just a pile of clay, the Djenneke join forces at the fête de crépissage. This documentary follows the preamble to the festival. The meeting of the amirs, the young ones who represent their district and organize the day. Their purchase of cigarettes and candy to reward the hard work. A visit to the marabout, to ask for protection during the work. The night before, with reggae blaring out from the ghetto-blaster and energy drink in the cool box. And at the same time the conflict between traditions and renewal. The troubles of a town preserving a unique identity. Throughout the storyline runs the tale of the many century old legend about the genesis of Djenné.
