On his first day as game warden in Saddlestring, Wyo., Joe Pickett finds himself in an unexpected situation with a local poacher.

Joe weasels his way into a local murder case and finds himself at odds with some important townsfolk; Marybeth manages the rest of the family at a motel and does some digging of her own.

As Joe and some other her brave locals embark on a dangerous trek, Marybeth contemplates going back to the courtroom for what seems like a worthy cause.

Joe enjoys newfound praise after dispatching the presumed murderer, but he isn't convinced the investigation is over; someone is attempting to clean up all the loose ends.

Joe and Marybeth are spooked after the incident at Clyde's trailer and must decide whether or not they want to continue looking for the truth; Sheridan gets an expected visitor.

Joe begins to wonder if there's anyone in this town who isn't connected to the deeply rooted corruption, and Marybeth works around the clock to try and free Nate.

Joe connects an important piece of the pipeline mystery, but it may cost him; the Pickett's find themselves in a luxurious new home.

In need of some breakthrough evidence, Joe calls in a favor from an unexpected ally; Marybeth and Sheridan remain vulnerably close to danger.

While Joe frantically rushes to the hospital, Sheridan tries to recall her survival skills to escape an unhinged predator.

In the final showdown, the Picketts face their toughest battle yet; when the dust settles, those who live will have to learn to move on and cope with the sacrifices they have made.
