A gang of bandits attacks the stagecoach carrying Hoss Cartwright and two nuns, elderly Mother Veronica (Ilka Windish) and young Sister Mary Kathleen (Judy Carne). When the younger of the nuns anxiously surrenders the money collected for a new convent hospital, the older nun rebukes her, informing the girl that she hasn't got what it takes to enter the sisterhood. Determined to prove her mettle to both Mother Veronica and herself, Sister Mary Kathleen sets out to recover the stolen money-with Hoss tagging along to make certain that the headstrong nun won't get in over her head. Written by Frank Cleaver, "A Question of Strength" first aired October 27, 1963. ~ Hal Erickson, Rovi
