In the fictional African nation Zambeze, American mining engineer Rick Morgan is conned into an illegal operation involving toxic waste by his old friend, Jim Scott. Immediately after, the mine is attacked by a team of mercenaries, led by a rogue agent called Chang. Scott attempts to flee, but is supposedly killed by Chang. The mercenaries leave right as the army arrives. The government assumes Morgan is responsible for the deaths of hundreds of villagers, apparently caused by toxic waste. Due to the CIA, Morgan is allowed to return to America.
