Kimble is working at a liquor store in a town where there recently have been robberies and killings at liquor stores. Herbie Grant (actor Warren Oates) comes in the store, points a gun at Kimble, and announces a robbery. Kimble coolly tries to discourage the robber, telling him the register is empty and he does not know the combination to the safe. Herbie starts to leave when the store owner comes from the back and shoots Herbie, wounding him in the leg. Herbie escapes.
When Kimble goes on a delivery, he finds Herbie in the back seat, asking for help at the point of a gun. Herbie insists that while guilty of this robbery, he had nothing to do with the other robberies where people were killed. As the episode proceeds, Kimble gets more involved with Herbie, and his sister Lorna Grant (actress Virginia Vincent). Lorna is torn by her distrust of Herbie and contempt for his low character (she calls him a rat), and her desire to help her brother. Meanwhile, the police, including Lt. Santelli (actor Malachi Throne) are investigating the matter, making Kimble quite uncomfortable.
Between police searching hard for Herbie, and Herbie's treachery, Kimble faces tough challenges to keep his promises, live up to his own ideals, and yet escape the police.
