In the gripping episode Grebb Hassle from Gunsmoke, Marshal Matt Dillon finds himself in a precarious situation following the death of Alvin Grebb, a known criminal. The episode opens with Dillon reflecting on the nature of his job, which often leaves him feeling isolated and burdened by the violence that surrounds him. Alvin's return to Dodge City after two years of absence raises alarms, especially for Dillon, who had previously warned him against returning. When Alvin is killed during a botched bank robbery, Dillon's concerns shift to Alvin's younger brother, Billy, who seems to be on a troubling path of his own.
