Congo

The search for diamonds, a crucial scientific breakthrough and a mythical ruined city set off this adventure into the heart of the Congolese jungle. The American expedition is led by Karen Ross, desperate to find her husband and recover the data he found before he disappeared. But there are other teams trying to get there first, and the way is strewn with life-threatening dangers -- plane crashes, civil wars and a dormant volcano awoken by dormant explosives.
