Dexter MacCandlass, and a team of FBI agents from the Southern California office investigate a suspected terrorist safe house. Mac's specialty: computer technology. Though the hostiles escape, Mac goes in to gather as much information from their computer as possible. The hostiles are then traced to Las Vegas.

In that city, another raid on their hideout is a disaster. Mac is kidnapped and taken to their safe house, and tortured for information he knows about the terrorists. He is dumped in St. George, Utah, (two hours from Las Vegas) left for dead.

Claire Talbot owns a veterinary clinic in St. George. She and a friend Suzanne Freeman, an ME (she is married to a cop in Las Vegas), rescue Mac and help him to recover. The terrorists plan on mass destruction in Las Vegas sometime during the last week in December.

It's up to these four plus other law enforcement to find the terrorists, their targets, and stop them.
