An all-new season of Ax Men explodes on to the scene. Swamp Man Shelby Stanga continues his search for the million-dollar log raft but a rough first day and a new opportunity change his mission. In Florida, the Dreadknots have a new deckhand and a new enemy. While in the northwest, last year's King of the Mountain winner Gabe Rygaard returns but this year he's defending his title with a whole new crew and without his dad. While in Alaska, the boys of Papac are back and ready to reclaim the title, but they face a site so treacherous it's considered to be unloggable.

The season is just beginning, and already, things are off to a rough start. At Rygaard, worried about his son's rocky start, Craig stops by and gets an unwelcome surprise of his own. In Alaska, Joe Linderborg and Mike Coatsy are taking two new greenhorns to school but it's looking like one of them might drop out. In the swamp, Shelby is loosing his assistant, his dog, his jet boat and his mind. In Florida, both Dreadknots and Chapman river teams are fighting just to stay afloat.

It's week three and the surprises keep on coming. In Washington, Gabe's king of the mountain title is in the hands of a novice crew, until he gets some help from an unlikely family member. Down in the swamp, Shelby's log buyer stops by for a surprise visit and things aren't looking good for the Swamp Man. On the Withlacoochee, the Kraken and Katelyn find that logging without Capitan Clint might not be as easy as they thought. At Chapman the newest member of the team fights for his life.

It's week four and the season is already running off the rails. On the Olympic Peninsula, Gabe runs a hung-over greenhorn into the ground but Jason disagrees with Gabe's management style.

In Washington, Gabe Rygaard is in over his head when a logging legend bails him out of trouble and gets him back in the race for King Of the Mountain. Down in Louisiana, Shelby and old friend Mike Chatellier use brute force to pull two of the biggest logs they have ever seen. With the Kraken injured, the Dreadknots bring in a new diver to brave the muddy waters of the Withlacoochee, but she soon finds out river logging isn't easy. Down on the Saint John's River, the Chapman team is pulling ahead, but a log poacher needs to be caught and Jeter is just the guy to do it.

The Rygaard family is back on the mountain and firing on all cylinders, until new yarder team Oakes Logging crashes onto the site, challenging Gabe face-to-face for the title of King of the Mountain. Down in the swamp, Shelby and Mike use redneck ingenuity to pull a huge and rare heart-pine log. In Alaska, the Papac team is down a yarder engineer, leaving them no choice but to make reckless Joe the new operator in order to stay in the race. In Florida, the Dreadknots newest diver Erin is finally getting the hang of river logging, but Kraken's fear of another diver taking his place causes a rift with Captain Clint. Meanwhile, the Chapman team gets revenge on a suspected log poacher.

In the bayou, Shelby goes diving in gator infested waters. Up north, rivals Rygaard and Oakes square off on a one-way road and a Rygaard driver is nearly killed when his truck flips. Down in Florida, the Dreadknots go their separate ways as Kraken and Katelyn set sail with their own boat.

Up in Alaska, Joe and Coatsy struggle to get the Papac crew back on track. In Florida, the Dreadknots have a run-in with fish and wildlife while the chapman crew works through the night to catch up in the log count.

As the loggers close in on the end of the season, one log could be the difference between winning and losing, reeling in fortunes or coming up short.
