Raging Sharks DVD

Oceania, an underwater seismic survey lab, picks up an unusual phenomenon from the ocean floor - a field of magnetic pulses that drive sharks into a frenzy. Dr. Mike Olsen (Corin Nemec - TV's Stargate SG-1), his wife Linda (Vanessa Angel - The Perfect Score), and their crew monitor the incredible convergence of hundreds of sharks around the "energy field". It's unlike anything they've ever seen before... Divers on a repair mission from Oceania are viciously attacked by the raging sharks and all life-support cables leading to the lab are severed. The oxygen supply is critical and the shark attacks have compromised the stability of the structure. The lab is in danger of collapse! What is really driving the sharks into a killing frenzy and can anyone get out alive?
