The humanitarian aid expedition Angeles Azules (Blue Angels), comprising twelve Europeans and six trucks loaded with provisions to alleviate hunger in Sub-Saharan Africa, advances across the continent. As a result of the difficulties the team encounters, disorganization gradually takes over the convoy.

But a starving local tribe settles threateningly near them. The chief of the tribe makes a speech they dont understand, which is followed by a macabre purification ceremony.
