As the Alaskan ice road season comes to a close, truckers have only a few runs left. Both the truckers and their rigs are running ragged as they race to pull in the last loads.

Lisa Kelly can't get out of the Carlile yard in Fairbanks - the trailer they've assigned her has a massive air leak. To stay in the running in the Dash for the Cash, she accepts a new load: a van full of high explosives. She's never hauled such volatile load before. When she gets on the Dalton she once again has trouble getting up the slope at 2 ½ mile. And later over Atigun pass, she battles deep snow drifts on her way over the summit.
