When a jury fails to convict the serial killer who savagely murdered his family, one man must rise above his desire for revenge and descend into the deranged world of a sadistic predator to uncover the truth and finally get justice. What begins as a classic revenge tale takes a dramatic turn into a haunting land of horror and murder.

On a remote former submarine refueling facility called Aquatica, a team of scientists are searching for a cure for Alzheimer’s disease. Dr. Susan McAlester genetically engineers three Mako sharks, intending to increase their brain capacity so that they can harvest the tissue as a cure for Alzheimer’s. Unfortunately, the increased brain capacity also makes the sharks smarter, faster, and more dangerous. Aquatica’s financial backers are skeptical and nervous about the tests, and send a corporate executive to visit the facility.
