For Navy SEAL Lieutenant Tom Paoletti an enforced medical leave of absence is the last thing he needs. As head of the Troubleshooters, an elite special ops unit, not only is Tom used to injury but he thrives on the danger that comes with his work. With little choice though, Tom heads home to New England, thinking that the sight of Dr Kelly Ashton, the sweet 'girl next door' from his youth, might help soften the blow.

Then Tom catches a terrifying glimpse of an international terrorist in his hometown and everything changes. His superiors are quick to dismiss Tom's warnings as paranoid delusions brought on by his near-fatal head injury, but Tom can't take the chance that the Merchant' may be planning a terrorist attack on US soil.

Convinced that the danger is very real, Tom pulls together a makeshift counterterrorist team. But in conditions like these, can Tom be any match for the Merchant?
