This one-hour special includes helicopter rescues on frigid, 22 degree mountaintops and dangerous suspect chase-downs in south central Alaska. In the Talkeetna Mountains, when snow machine riders go missing, Trooper Mel Nading and rescue volunteer Scott Horacek deploy on a search and rescue mission. The search via helicopter comes across an overturned snow machine, and in 22 degree weather, the race is on to find survivors.
