Zanzibar plot
"Captured...a victim for the sacrificial altar...because she dared solve the secret of the darkest continent!"
Commissioned by the British government, Jan Browning and Steve Marland embark on a journey of discovery through the African wilderness. Jan and Steve join an expedition in Zanzibar in search of the sacred skull of a long-dead sultan. The myth goes that whoever has access to this skull will have total control over the local indigenous people. That is also the reason that a number of sinister gentlemen with a German accent prey on this skull. Along the way, however, both groups are confronted with a volcanic eruption, which will have unpleasant consequences for them.
