But when he and his crew are diverted to rescue an imperiled Army research team, trouble is exactly what they find. “Running silent” in their unarmed sub to avoid detection by a hostile fleet, they bring the researchers and their top-secret cargo aboard. But when that cargo – including two genetically enhanced leviathans – escapes captivity, the crew find themselves battling deadly enemies above the surface and below foot in this fast-paced film filled with biting action and slithering suspense!
