The Breaking of the Habit - S4.E19

After fleeing a police roadblock where he gets shot in the leg, Kimble hops on a truck headed toward Sacramento where he meets Sister Veronica (the nun whom he drove from Nevada to Sacramento in the 'Angels Travel on Lonely Roads' episodes) whom is now the principal of the St. Mary Magdalene School for girls. Kimble asks Sister Veronica to drive him to Tarlton, where the one-armed man supposedly works as a numbers runner for a local racketeer. But a 'bad-girl' student recognizes Kimble and calls the police, forcing Kimble to hide on the roof of a building despite his injury. Meanwhile, Sister Veronica (whom is suffering from a brain tumor) learns that another delinquent student has run away, and is torn between driving after the girl or staying to help Kimble.
