The Rifleman/Six Years and a Day
From The TV IV
Mark and Lucas are trying to help the Marstons who are in dire need of medical help. Sarah Marston is about to give birth and it isn't going to be easy. When Mark goes to North Fork to fetch Doc Burrage, he learns that he is out of town and won't be back until the nest morning. Two men follow Mark back to the McCain ranch and take everyone prisoner. They mean them no harm but it's clear that they want North Fork's doctor dead and plan on waiting until he arrives the next morning. Lucas wants to get a midwife to help out but can't leave and it's not clear that Sarah will last until morning.
