Megalodon Rising

In international waters, a Chinese military cruiser experiments with beam-forming tech. It creates powerful high frequency vibrations -- crewmembers wear protective headphones. Suddenly, a giant creature (one of the Megalodon offspring) attacks.As the ship is devoured, and the beam-forming, high frequency tech now sinking, the crew sends off a warning signal. A US ship is patrolling on her military cruiser about 50 miles out from San Diego where she finds the Chinese military ship's only survivor -- lead scientist, Dr. Jaing Lee.The Chinese military arrives, threatening the US ship if they don't return, back at base the order goes out not to fire on the Chinese ship or they will have WWIII on their hands. A triangle of danger with the Megalodon, Americans and Chinese all seeking victory.
