With the help of his ex-fiancee, the beautiful Korean born State Trooper Lonnie Wyatt, and the chance reunion of his old special operations buddy Harley Wasner, they race to stop a potentially devastating terrorist attack with worldwide implications but even nature is against them as the temperatures plummet to 65 below.
