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. On the road, he shows her how to avoid spinning out by shifting gears. Hugh and Phil have been doing short turns all week to get storm-delayed freight from Coldfoot to Deadhorse. On today's trip, Hugh discovers that he and Alex are not the only fierce competitors on the ice road. Phil is battling with his nemesis at Carlile, Drew---they get into a heated debate on the CB about who has the most trips this month. Since Hugh's logs are same as Phil's, he thinks they will win this one. Tim and George are delayed again in Fairbanks because George's truck is in the shop. But when they finally get on the road, it's Tim's truck that develops a fatal electrical problem. The rookie is severely disappointed and has to turn back again while George carries on north by himself.

I Manitoba, Canada, kæmper Alex, Hugh og Ross for at levere deres varer på trods af de hårde vejforhold. I Alaska vender Ace Jack tilbage med tre nye truckers: Darrel, Austin og Ron.

Alex kører på det Ishavet til den nordligste canadiske landsby, der er tilgængelig ad isvejen. Hugh og Rick må gennem smeltende is i en desperat søgen efter manglende trailere.

I Alaska tikker uret, da fristen for at levere en stor olieplatform presser alle truckers til at give den hele armen. Men er presset for meget for én bestemt nybegynder?

Sæsonens største storm rammer Haul Road. En trailer-funktionsfejl gør at Jack Jessee er i fare for at blive strandet, mens stormen nærmer sig. Darrell forsøger at komme igennem det umulige vejr.

Nu hvor Dalton er lukket, kæmper alle truckers en brav kamp for at levere i tide. I Manitoba er vintervejene blevet brutalt varme hvilket har gjort det næsten umuligt at køre.
