Like shadows in the night, Captain Andrew Serrano and his elite team intercept the cargo ship Griffin, secretly owned by a Russian arms dealer. Their objective: capture the bio-engineer Dr. Hank Nore and deliver him to the C.I.A. The operation initially goes well, with the team overpowering the security forces and tracking their target to the lower decks. Backed into a corner, Dr. Nore resorts to desperate measures to avoid capture. When explosives breach the hull, the mercenaries are forced topside before the vessel sinks to the bottom of the Indian Ocean. Minutes later, they find themselves stranded on floating wreckage. Little do they know, their nightmare has only just begun. A large dorsal fin rises from the water. One of their numbers is quickly pulled under and torn to pieces. In that moment, Serrano realizes he and his team are being stalked by a ravenous shark. Before long, it becomes evident this is not a normal shark, but a product of genetic tampering. Mutated from the October Trial of the Titan Serum experimentations, the creature seeks to kill without discrimination. With bulletproof skin and armed with teeth sharp enough to pierce steel, it is the prototype for new age of biological warfare. With his team being massacred before his very eyes, Serrano’s only chance for survival is to rid the world of The Titan Prototype.
