This installment of "The Fugitive" is a cheesy tear-jerker with a plot which depends heavily on (spoiler-alert!) a deus-ex-machina moment. But it's a surprisingly effective tear-jerker. I cried like a baby, more than the one in the story. What makes it convincing is really good acting by magisterial Harry Townes, and by understated Tom Skeeritt, and by overstated Kim Darby, (who provides some ham to go with the cheesiness of it all. This episode aired just ten days before her "Star Trek" episode in which she played a less grown-up variant of the same character she plays here.)
