Silent and lethal, USS Seawolf, the US Navy's state of the art stealth submarine, is on an ultra secret mission - to spy on China's brand new, XIA-class submarine. The XIA is the menacing flagship of China's navy, and with American security under greater threat than ever, Seawolf's mission is urgent . So much so that it is forced into hugely dangerous waters where disaster is moments away. Late one night an executive officer makes a shocking mistake and collides with a Chinese warship. Seawolf's entire crew is taken captive, and the Chinese Commander in Chief, all too aware that the US government will try to rescue their sailors, has them moved to a top security prison. With the SEAL team on their way, the Chinese are unaware that among their captives is a mysterious officer whose real identity has been carefully hidden, even from his fellow crew members. It's a race against the clock in which the stakes are almost too high to bear.
