Jesse's (Sharon Stone) father has gone missing in Africa, and she has hired Quatermain (Richard Chamberlain) to help her find him. In fact her father has discovered the location of King Solomon's fabled mine and massive diamond wealth. Unfortunately the unscrupulous Colonel Bockner (Herbert Lom) and Dogati (John Rhys-Davies) have captured him and are trying to get the information out of him by fair means or foul (actually no just foul)...
Their adventure becomes a series of exciting though somewhat improbable action set pieces across Africa including on a train and in the air. All the time our heroes are trying to avoid getting eaten by wildlife and the natives...
A very silly film, a well done parody of Indiana Jones and the like. The jokes are corny and the action frequently improbable but that is the point. Very entertaining.
