Every summer thousands of families head to the nation's largest water
park, famous for its 21-story waterslide, the Dead Drop. This year one
visitor didn't pack his bathing suit. He packed explosives. When the
bomb goes off, dozens of people are instantly killed. The rest are
herded into the park's massive pool by the bomber's accomplices. An
organized team of fanatical but well-trained terrorists, they seal off
the entrances, turn the waterslide into a watchtower, and train their
sights on the families below. But one hostage isn't playing along. He's
special agent Jericho Quinn. He's on vacation with his daughter. And
he's about to turn this terrorist pool party into one righteous blood
bath....
