Stern is a doctor who has affiliation with the Dixie Mafia.
In "Bloody Harlan", he is called upon by Boyd Crowder to watch over and help Ava after she was shot by Dickie Bennett in the chest.
In "Thick as Mud", Boyd invites him down to his bar. Stern asks Boyd if Ava has been doing her exercises for rehabiliation, but Boyd tells him he isn't there to talk about Ava. Boyd reveals that he knows that Stern has been writing prescriptions for protection and Oxy, and Stern reveals that Frankfurt (Dixie Mafia) was offering. Boyd asks him to sell the Oxy and give him the profits, but Stern says that if he does that, they will kill him. Boyd says that they will protect him, but threatens his mother if Stern refuses to help Boyd.
In "When the Guns Come Out", Stern is now working for Boyd, selling the Oxy and shipping him the money. Trixie and Ellen May visit him wanting Oxy in a big bottle, but Stern gives them a smaller bottle and tells them that is all they are getting. The two girls soon attempt to resort to seducing Stern so that he gives them more oxy. Tanner Dodd and Teddy bust into the house, and they shoot and kill Rip who is keeping watch in the living room. Stern pulls out a handgun from a drawer in his desk, but Tanner shoots him in the stomach, as well as shooting Trixie. Stern is then shot one final time by Tanner, which kills him.
