Lifelong Texan Jerry Campbell has been in the hog hunting game for over half a century. His kids, Robert and Krystal, are hoping to turn Dad's lifestyle into a full-time family business helping desperate landowners clear their property of destructive wild boars that are causing millions of dollars in damage. The family takes on their first job at a nearby ranch, but when their lead hunting dog, Rooster, disappears in the middle of the hunt, the family has to find a way to finish the job without him.

After the loss of his lead hunting dog, Rooster, Jerry is ready to call off the hunts for a while he trains a new dog. But Krystal and Robert are desperate to keep their fledgling business alive. Against Jerry's advice, Robert invests in a new dog, Creager, hoping he can lead the pack. But a hunt at an auto salvage yard leaves Jerry with doubts over the new dog's abilities. When a call comes in from a ranch owner with livestock being eaten by hogs, Jerry and the kids take the job. The future of the family business, and Robert's reputation, depend on whether the new dog has what it takes to replace Rooster.

The Campbells get a call from an elderly widow being terrorized by a massive 250-pound boar. At the job, the battle between Jerry's old ways and the kids' new methods turns the hunt into a family feud that descends into chaos. In order to catch the giant hog, the Campbells will have to work together and agree on an approach. But with tension at the breaking point, it may finally be time for the kids to take the reigns from Jerry.

The Campbells and their team of young dogs tee off at a Texas golf course, where an aggressive hog is threatening golfers and tearing up $20,000 greens. But the hunt leaves Krystal and Robert concerned about Jerry's health and ability to keep hunting. A call comes in from a pecan orchard overrun with hogs, but when the kids try to take some of the workload off Jerry, the pressure of leading the hunt leaves Krystal and Robert fighting each other instead of the boars. When Jerry goes missing during the night, attention shifts to finding the family patriarch.

The Campbells are faced with their biggest job yet: a 900-acre deer hunting ranch overrun with boars. Hoping to increase their hog hunting arsenal, Robert sinks more money into the family business by buying a hog trap. Jerry, who prefers hunting exclusively with dogs, forces Robert to prove the value of his investment by challenging him to a $1,000 wager over who will catch the most hogs. Meanwhile, the sheer size of the job has the family feeling overwhelmed. With their reputation as hog hunters on the line, the Campbells are forced to hunt through the night using any means necessary to rid the ranch of boars.

After taking to the internet to find new customers, Robert and Krystal find a hog hunting job at a local vineyard. But working close to the delicate grape vines forces the family to replace Jerry's traditional hunting methods with Robert's new strategy. Never happy to take a backseat, Jerry looks for hunting work in the farming community of Haskell, Texas. There, wild hogs are decimating peanut crops and Jerry's convinced his old-school methods are the only way to save the farmers. But with the kids determined to do things their way, the family business is in danger of being torn apart.

The Campbells tackle their biggest job yet: a ranch so overrun with hogs, the owners are on the verge of selling the property. But the size of the ranch has Jerry worried about the safety of taking the job. On the hunt, Jerry finds signs of massive numbers of aggressive hogs, but the property is so large the kids are out of radio range. Split apart and facing a huge pack of boars, the Campbells might have finally met their match.

After nearly facing defeat on the 4R Ranch, the Campbells gear up for one last stand. Scouting from a helicopter, Jerry thinks he may have finally found where the elusive hogs have been hiding. But on the ground, their luck changes for the worse when the pack of aggressive hogs takes Robert, Krystal, and Lea by surprise, forcing them into a battle for their lives. With everything on the line, the Campbells are determined to clear the 4R Ranch, or die trying.
