Discovery's smash-hit original Canadian series returns for another epic season, with 17 all-new episodes following the hardworking and heroic heavy recovery operators who fight to keep the roads open through British Columbia's Coquihalla and Cascade mountains. This season, Jamie Davis continues to lean on his classic collection of "old iron" to tackle some of the toughest recoveries, but his crew is buzzing with excitement at the prospect of something shiny and new coming to the yard. Change is also in the air for lead-operator Colin Mclean, when developments in his personal life lead him to question his future in the tow business. Then, 100 kilometers north of Hope, B.C., Reliable Towing's resilience is tested like never before when one of their own is caught up in a terrifying event on the highway. Quiring Towing's Al Quiring and Gord Boyd tackle some of the heaviest off-road jobs imaginable, while down in the Fraser Valley at Aggressive Towing, Jamie's brother Jason and his top man Chris ‘Merv' Mervyn's modern rotators are in high demand. Just down the road, 63-year-old heavy rescue legend Ken Duperon continues to lead Mission Towing, but when he's struck down by an urgent medical crisis, his son-in-law and lead-driver Dylan Greenwood must step up. HIGHWAY THRU HELL marks its milestone 100th episode this season, before just-announced Season 9 begins production.
