IRT Deadliest Roads

Alabama trucker Dave Redmon stares down the notorious Freefall Freeway in a truck that is in horrible need of repair. Roadside maintenance costs him valuable time and he must face driving the roads with terrifying drop-offs at night or risk being late with his very first load. Lisa heads back up to The Ledge, the narrow stretch of road that caused her to quit the last time she drove it. But this time, a flat tire leaves her teetering on the edge of the abyss. And the crowded roads finally bring Rick to the breaking point. The oncoming traffic sends him into an angry fit on the side of the road and when his greatest rival--the aggressive bus driver--attempts to pass him on a narrow stretch, Rick refuses to back down, even with oncoming traffic bearing down on them both.

After receiving more good news from home, Rick decides to stay. He and Lisa drive higher into the Himalayas than ever before with fragile statues of a Hindu goddess. Rockslides and tight roads force the drivers into dangerous situations, and risk breaking the sacred statue--making the whole trip worthless. Dave tackles the notorious "Ledge" for the first time, all while dealing with an oversized load and oncoming traffic.

After conquering the Freefall Freeway, the Cutouts, and the Ledge, all three drivers climb higher, to over 13,000 feet, as they tackle the Rohtang Pass for the first time. Rick delivers a sacred Buddha statue between monasteries. Lisa brings much needed supplies into Keylong--a city normally cut off by snowy winters. Now the snow's melting, and roads are falling apart under rivers and gushing waterfalls.

After a severe storm strands Rick, Lisa, and Dave in Keylong, Rick leads the charge back over the Rohtang Pass, betting against Mother Nature and the dangerous road. Dave and Rick deal with an aggressive Indian driver, and after the drivers hit their boiling point, they all get caught in a landslide.

Tensions hit a high point between Lisa her spotter Tashi, forcing Lisa to think about saying goodbye to Tashi and forging ahead alone. Dave's forced to stop in the middle of his run to deal with his overweight load. Rick battles through illness to make his trip on time, giving everything he can into delivering on time.

A snowstorm threatens to cut the drivers' runs short atop the Rohtang pass. Rick's spotter Boyo leaves Rick for a better job, forcing Rick to go it alone. Lisa and Dave drive as fast as they can to beat the storm, but are slowed by mobs of people on the pass. All three drivers get caught driving in darkness and Lisa battles fatigue--struggling to stay awake.

As the season comes to a close, the drivers have one last assignment, and it's their most dangerous and important: deliver barrels of aviation fuel for helicopter rescue missions. Rick and Lisa are going on alone, with no spotters to help on the snowy roads. Dave learns he's not out of the woods yet and gets in yet another accident. And at the end, only one driver completes the final load.
