Suicide rates are climbing in native Alaskan communities, and troopers race to save a woman holding a gun to her head. Meanwhile, troopers police the island of Little Diomede, located just over two miles from Russia in the Bering Strait. With temperatures of -40¯ and wind gusts up to 80 mph, catching criminals here is uniquely challenging. Troopers must fly in and land on the ice-covered Bering Strait, apprehend a sex offender, and transport him via snowmobile and plane back to the mainland.
