In a remote, frozen corner of New Hampshire, a Navy SEAL team and the elite security experts of Troubleshooters, Incorporated are going head-to-head as fierce but friendly rivals in a raid-and-rescue training exercise. Despite the frigid winter temperatures, tension smolders between veteran SEAL Petty Officer Mark “Jenk” Jenkins and former cop turned Troubleshooter Lindsey Fontaine after an impulsive night goes awry. And then, suddenly, Tracy Shapiro, the Troubleshooters’ new receptionist, vanishes while playing the role of hostage during a mock rescue operation.
