A new competitor on the Coq has cut Jamie's business in half, and the one job he lands in weeks ends up being a complex recovery that no one seems willing to pay for. Heavy rescue faces a life and death decision - shut down or leave the Coq for the oil rush boomtown of Fort McMurray and some steady cash. Determined that "closure is not an option" for Jamie Davis Heavy Rescue, the crew packs up and heads north in search of the new highway thru hell.
Adam and Jamie are forced to use some fancy rigging to try to save a wreck on Highway 1 that threatens to spill its load all over the road. When a new competitor rolls onto the mountain and cuts the work in half Jamie is forced to realize he can't afford to keep his world class fleet of trucks on the Coq.
Heavy rescue has to recover a severely damaged trailer loaded with millions of plastic beads. Spring rains are causing rock slides on Highway 1. When a B-train loaded with lumber drives off a cliff in order to avoid a boulder, Jamie's called in to recover the wreck before it falls down onto an active railroad line.
A trailer filled with costly pharmaceuticals gets imbedded in a block of ice. A truckload of frozen chickens crashes into a tangle of trees. 65-year-old Bruce begins to show signs that he may be over the hill. Rob's promotion to lead flagger is short-lived when police revoke his license for speeding.
Tension between Jamie and Adam boil over as they struggle to flip a B-train on a narrow icy road. Adam comes close to quitting, but then backs off when Jamie makes him a promise. A two-car collision closes the snow shed and puts Ken's towing know-how to the test. A truckload of Christmas mail nearly goes off a cliff.
Jamie brings back veteran driver Scott by promising him a new state of the art heavy wrecker. But the new truck is months behind schedule, so Scott has to settle for a worn-out vintage truck. A grueling schedule pushes Adam to his breaking point and he goes AWOL, while Jamie is forced to abandon his Rotator on a backcountry road that is too dangerous to drive.
The closures of two major highways cause drivers to voice their frustration leaving Gazzola in a sour mood over all the grief he receives. Ken Monkhouse arrives at a job to find that the competition has gotten the jump on him. Responding to a woodchip wreck, Davis, Gazzola and Ritchie disagree on how to recover the wreck, leaving Davis to do his own swamping. Later, when a heavy SeaCan tips over, Davis and his rotator are pushed to their limit. Monkhouse, realizing he needs help in the car towing division, invites Kodallas for a lesson in a new truck, but Kodallas has words with his stepfather and walks off in a huff. Monkhouse then turns to the new guy - quiet, tattooed Lundin - testing him out on a tough tow lesson.
Jamie Davis, eager for the winter season to begin, has one thing on his mind - amp up his manpower and his equipment, so he's ready for anything that happens on the mountain. He has brought back a big crew - Adam Gazzola, Narayan Samy, Kevin Ritchie, Rob Mitchell, Bruce Hardy, Ken Monkhouse, the new guy Gord Lundin, and Davis' stepson Brandon Kodallas. Everyone has big, but not always realistic, expectations for the winter ahead.
