Experimenting with shark DNA in his remote laboratory to discover the cure for end-stage diseases, the zealous bio-scientist, Dr Preston King, invites a team of doctors, his wife, and her latest boyfriend to the island to witness the progress of his research. But, there, the unsuspecting visitors will come face-to-face with the true nature of King's highly questionable procedures, as a monstrous half-man/half-shark hybrid who knows no fear roams the area, hungry for human flesh. Is there an escape from the powerful jaws of the hideous Hammerhead? Written by Nick Riganas

Did You Know?


Dr. King comments that there has never been a known instance of a shark with a tumor. This is not true. Although sharks, like all members of the class Chondrichthyes, characterized by a cartilaginous skeleton and placoid scales, have genetically developed the ability to inhibit the secretion of angiogenin, a hormone necessary for tumor growth, the Smithsonian Institution has on record at least 15 instances of elasmobranch tumors; however, only two of those are thought to be malignant.

Did Combs lose a bet?
28 April 2006 | by jasonhalasSee all my reviews

This movie makes me think the others I've seen with Combs were an accident. The plot had more holes than I think I've ever seen in a movie purporting to be something more than a "b" movie. The acting was so laughable that not even the memories of Combs' past campy triumphs were enough to save it. Considering the script I have to imagine that there was not enough money in the budget for things like continuity and original ideas. I am thoroughly upset that I paid Blockbuster prices for this trash. The fact that it was made for television was something that would have helped me avoid this atrocity and frankly something that movies this poor should be required to warn you of. Avoid this movie no matter what.
