Before he can continue with his experiment, he tries to enlist Misty Calhoun, a shark conservationist, and other scientists to lead and endorse this project. The drug-enhanced sharks quickly begin to adapt and learn new hunting skills. The humans lose control over the laboratory and now they have to fight to survive. Deep Blue Sea Researchers on the undersea lab Aquatica have genetically altered the brains of captive sharks to develop a cure for Alzheimer's disease. There's an unexpected side effect: the critters got smarter... and meaner.
