Would you rather watch Deep Blue Sea or listen to Deep Blue Something? It's your life. We watched the movie. What do you think about that?
On an island research facility, Dr Susan McAlester (Saffron Burrows) is harvesting the brain tissue of DNA-altered sharks as a possible cure for Alzheimer's disease. When the facility's backers send an executive (Samuel L. Jackson) to investigate the experiments, a routine procedure goes awry, and a shark starts attacking the researchers. Now, with sharks outnumbering their human captors, McAlester and her team must figure out a way to stop them from escaping to the ocean and breeding.
