When the death rate of sperm whales rises dramatically, a well-respected environmental activist puts together a ragtag team to hit the high seas to investigate the matter. They suspect that the deaths are due to poachers and they are all driven by a need for justice. Elsewhere, an experimental government vessel is enhancing deep sea mining equipment. They see one of these dead whales up close and personal...and are fairly certain that it wasn't poachers that killed it. Both of these teams are about to discover that poachers are the least of their worries. There is something hunting the whales... Something big Something prehistoric. Something terrifying. MEGATOOTH
