Highway Thru Hell Season 4

When winter strikes, Jamie's crew has to save a snowplow stuck in the grip of an icy river. Jamie pushes further into new territory, changes rock the company and the entire community says goodbye to a Heavy Rescue legend.

Jamie's new crew in British Columbia struggles with a mangled trailer on a blind and icy corner of highway 3. When Colin slips up on a big recovery in Alberta, Jamie's brother has to take over the job - even though he's new to the rotator.

When a lumber truck and diesel tanker collide... the flaming wreckage becomes the biggest recovery of Colin's career. As snowstorms pummel the Coquihalla, Al Quiring heads up the hill, ready for battle. In freezing rain...John faces off against a mangled tractor and becomes a mentor in the process.

Al and Gord battle through a stormy night to keep the Coquihalla Highway open for Christmas. A semi plows off a bridge, stranding holiday travelers, and a remote logging road job forces Ken to relive his close call from last year.

Al Quiring is in a high-pressure race to open the TransCanada Highway before rush hour. Jordie from Mission Towing faces a semi ready to split in two. Jamie Davis is running a race too when a pharmaceutical truck plunges down a bank.

Freezing rain covers Hope in a thick layer of ice, crippling Jamie's operations. A good friend of Jamie's is called into action when two semis collide head on, leaving wreckage scattered across the TransCanada Highway and a major rail line.

Al and Gord work to rescue a loaded semi that's teetering on the edge of a 300-foot drop. Colin faces a white-knuckle drive on a remote Alberta back road, and Jamie tests out a new driver, who might be in over his head.

When Jamie and Jason Davis Heavy Recovery crews team up for a massive wreck, a close call forces Brandon to reconsider his future in the business; in Alberta, attempts to straighten out a jackknifed truck get twisted in unexpected directions.

Strategies collide when the Davis and Quiring families team up for a rare joint recovery that shuts down the busiest highway in B.C.; on the Coquihalla Highway, a big rig is left teetering in a seemingly impossible position.

A simple job turns into an urgent puzzle when a flipped semi pulls Jamie back out on the road; Randy Jacknife faces one of the biggest and heaviest challenges of his career against an overturned truck trapped under its load of steel.

Al and Gord gamble on a job that's closed the highway and pushed both green wreckers to the limits; in Alberta, Jamie's crew battles a whiteout to reach a chain reaction wreck; in B.C., a wrecker is called in to help solve an underwater mystery.

As Jamie reaches a difficult crossroads, he looks back over four seasons, revisiting his most challenging wrecks and recoveries; familiar faces from past and present explain what drives them to this dangerous world; a look behind the cameras.

Jamie takes control of the rotator for the first time in months; Jamie turns to his competition for advice about a major decision that will determine the future of Heavy Rescue.
