Le convoi de l'extrême : le grand frisson

Day 1 of the new Ice Road season begins. There are 6,000 loads of freight to move in just 12 weeks to the oil camps of Alaska's North Slope. The 400 plus miles stretch from Fairbanks to the remote outpost of Deadhorse, is fraught with harrowing danger.

On Alaska's North Slope, a new ice road season has just begun. Carlile Transportation has less than three months to haul 2,000 loads from Fairbanks to Deadhorse--the gateway to the Prudhoe Bay oil fields.

It's three weeks into the winter season in Northern Alaska, and Carlile Transportation has only moved 500 of the 2,000 loads it needs to transport to the Prudhoe Bay oil fields. The clock is ticking and an arctic storm is brewing.

A massive storm blows in and all traffic on the ice road comes to a standstill. And if wheels aren't turning, no one's earning. George, Tim and Lisa take shelter at Coldfoot.

Another winter storm drops nearly a foot of fresh, new snow, obscuring the road south.

Lisa Kelly auditions to be the first woman to break into the elite Heavy Haul division by commanding a convoy of pilot cars while hauling 80-foot sections of wide-gauge pipe.

The race is on to make it to Prudhoe before a wicked storm turns fierce. After riding out the previous night's storm in Coldfoot, Tim and George decide to push on, despite the dire forecast.

A deadly combination of unpredictable weather on the North Slope has made Atigun Pass more dangerous than ever. Record snowfall mixed with now warmer temperatures has turned this wicked pass into a devil's slide.

With just three weeks to go, everyone is pushing it to the limit to get the freight to Deadhorse before the season ends. Lisa rushes to Carlile to pick up her next load. She's convoying north with Jack Jesse.

There's only two weeks left to pull in the big bucks and get all the loads to the oil fields. Hugh's impatience with his trainer driver Phil's slow pace nearly causes him to spin out on one of the steep slopes of the Atigun Pass.

With only two weeks left of the winter season, the race is on to deliver the remaining loads before the ice roads melt away. But this late in the game, truckers are besieged by mechanical breakdowns and a volcanic eruption in Southern Alaska.

The truckers and their rigs are running ragged as they race to pull in the last loads. Lisa can't get out of the Carlile yard in Fairbanks--the trailer they've assigned her has a massive air leak.

As the final 72 hours of the Ice Road season tick away, legendary driver George Spears calls it a career, Lisa Kelly makes a harrowing 300-mile run with no brakes.
