The ice road season opens and quickly claims its first victim with a road-closing wreck. Meanwhile, another trucker breaks through the ice enroute to the isolated town of Bettles. Jack returns to defend his title as "King of the Haul Road," but cocky second-year driver Greg is out to take him down and has something to prove.

Failing trailer brakes and trash talk over the CB threaten to derail Lisa's comeback. Newcomer Greg races to reignite his rivalry with Jack, before a devastating wreck slams the brakes on Greg's need for speed. In the meantime, with a damaged fuel tank to deliver, Jack isn't giving up the load-count crown without a fight.

The brutal Alaskan winter hits Prudhoe Bay with a vengeance, unleashing a ruthless windstorm. It takes nerves of steel to drive in these conditions but Jack, Hugh and Alex hit the haul road ready for battle, with near misses and disastrous engine trouble threatening to take them down.

A monster phase-3 storm is hammering Atigun Pass, and if they want to survive, the Ice Road Truckers will have to think fast. Alex is southbound from Prudhoe when he meets the massive blow, and whiteout conditions erase the road from his view.

Jack Jesse rushes to save an Alaskan town with an emergency fuel delivery, but a blinding storm stops him cold on the thin ice of the frozen river road to Nuiqsut. Lisa Kelly gets her big chance to step up when she's given her first oversize load, but as she battles the elements and the law, Lisa wonders if her trucking skills are up to the test.

The pressure on the drivers builds and hot tempers flare as the temperatures plunge to 55 below. Jack gets into it with a southbound driver who raises hell after a near head-on collision with Jack's oversized load on a curve. And Hugh gets an earful from an American driver who wants Hugh off the Alaskan roads and back in Canada. Meanwhile, Alex takes a big risk by picking up a hitchhiker.

When an avalanche strikes, Jack is stranded and left helpless as he watches the DOT clean up the carnage. Ray faces the Dalton with a premonition of death hanging over his head. Lisa fights to get back in the race. Hugh risks a head on collision at 4700 feet by driving on the wrong side of the road over Atigun pass.

Lisa tackles the most dangerous haul of the season, trucking a multi-million dollar, 100 ton load across the entire state of Alaska. This could be her ticket to the big leagues, or it could be a career killer. Alex races to keep pace in the load count and Greg could be a hero of the road.

It's chaos on the Dalton when a truck flips off the road and smashes into a tree, leaving two men injured and bleeding while a mysterious third is missing. Alex is thrust into the turmoil and faces tough questions from state police. A careless mistake may rob Lisa of the hard-earned respect she has worked for all season.

King of the haul road, Jack Jesse, must survive the arctic wilderness and cross a frozen river alone to reach the isolated town of Bettles. After ditching her truck, Lisa Kelly is back in action but the slippery slopes of the Dalton will make her road to redemption a dangerous one.

Dalton rookie Ray Veilleux drives into a trucker's worst nightmare when he's distracted for a split-second. With the king of the haul road battle getting fierce, his days as co-leader could be over. Lisa roars up the Dalton with an unwieldy bear cage in tow. And trouble is heating up for the Polar Bear when he ignores his poorly loaded cargo and causes damage to his latest load.

The Ice Road takes no prisoners when the truckers push their limits. Ray spins out into oncoming big rigs. Jack battles a 200 ton monster haul to Prudhoe. Alex risks a bust by the DOT. Lisa races to raise cash to buy back her horse. Greg drives into mega mechanical problems.

The Ice Road Truckers form a convoy for the first time ever to take on a most dangerous mission: as rising temps turn the ice road to Nuiqsut back into a river, they must cross the softening ice to deliver critical supplies while avoiding a watery grave.

When a Haul Road legend dies, Ray leads the trucker's son to scatter his ashes on Atigun. But the son's blunders on the Dalton could get them killed before they make it. Lisa gets her biggest break yet when she's assigned to push-truck a monster load to Prudhoe. Alex discovers Alaskan gold, but is later busted by the DOT for violations.

As Alaskan temperatures rise, it's heading into the deadliest and most dangerous time of the year--the melt. Last year flowing ice from the Yukon River nearly wiped out an entire village. Now, the DOT are racing to stop an overflow that could take out the Dalton and its truckers with it. As drivers race to rack up loads in the Dash for the Cash, they're forced to team up for safety.

The Ice Road truckers battle to the last load to determine this year's King of the Haul Road. Tensions between co-leaders Ray and Greg explode on Atigun, giving Hugh a chance to take the lead. Lisa's possible best season ever is on the line, while Jack's hope to repeat as King is in jeopardy. Alex pushes to finally beat his nemesis, the Polar Bear.
