Captain Jack Boxer has orders to carry out an assault-and-rescue mission...

Captain Jack Boxer and the crew of America's high-tech submarine Shark are temporarily assigned duty on the experimental submarine USS Turtle.

The Turtle has been designed to travel overland as easily as beneath the sea - the ideal vessel to spirit a Special Forces team into a prison camp to bring out a group of prisoners with information vital to the military high command.

The top brass know the dangers of sending a radically new and untested submarine into battle, but for them the gains outweigh the risks.

And every man aboard the Turtle knows the risks will be measured by victory or death.

With the odds against them, can they complete the mission?

To succeed they are going to have to fight their way in - and out...
