Gunsmoke #379, "Friends Payoff," opens with a mysterious boy delivering an urgent message to Marshal Matt Dillon, refusing to show it to anyone else despite Chester's protests. The note leads Matt out of town to a deserted shack where he finds Ab Butler, an old friend, badly wounded from a back-shooting ambush on the trail from Texas. Ab is desperate to stay hidden, convinced that whoever shot him will come looking to finish the job. Matt gets him to Doc Adams for treatment, and Doc manages to remove the bullet, though Ab remains weak from blood loss and his chances are uncertain.

As Ab recovers in Doc's back room, a stranger named Joe Leeds arrives in Dodge asking questions all over town about Ab Butler. When Matt confronts him, Leeds makes it clear he's tracking Ab for personal reasons and has no intention of involving the law. He promises that when he finds Ab, their business will be settled quickly and privately. Matt warns Leeds that he'll be watching, but the gunman remains determined to handle matters his own way, setting up a tense standoff between Matt's duty to protect his old friend and Leeds' relentless pursuit.
