RIVER OF FIRE
Six scientists came to this South American jungle in search of the gas emissions people of the area reported smelling; now there is only two, Tom High Moon and Judy Brown left to tell their story. Jane Wells, Angie Blake, Bill Wong and Joe Erickson are dead.
They had followed the smell up the river deeper into the jungle where they found a cave emitting the gaseous smell. On entering the cave, the scientists some how started a flash fire that killed four of the team. This is now chasing Tom and Judy down the river.
