The horror film Megalodon begins as a large corporation begins using a powerful drill in order to look for oil in Greenland. The company disregards the warnings of scientists who claim that the drill may disrupt the natural order of the environment. The drill eventually goes so deep that a new ocean is discovered. In that ocean is a deadly ancestor of the white shark, Carcharodon Megalodon. The creature weighs more than twenty-thousand pounds and begins working its way toward the crew that worked the drill.
